[netdrvr mv643xx] This patch removes code that is redundant or useless.
The biggest area is in pre-initializing the RX and TX descriptor
rings, which only obfuscates the driver since the ring data is
overwritten without being used.

[netdrvr mv643xx] This patch removes spin delays (count to 1000000, ugh) and instead

<dale@farnsworth.org>
[netdrvr mv643xx] This patch adds device driver model support to the mv643xx_eth
driver.
This is a change to the driver's programming interface. Platform
code must now pass in the address of the MV643xx ethernet registers
and IRQ. If firmware doesn't set the MAC address, platform code
must also pass in the MAC address.
Also, note that local MV_READ/MV_WRITE macros are used rather than using global
macros. Keeping the macro names minimizes the patch size. The names will be changed to
mv_read/mv_write in a later cosmetic cleanup patch.

[CIFS] get rid of tcp peek usage on cifs socket. Makes more sense to read
normally
first four bytes off the socket (then read the rest of the frame) rather than peek
first few bytes then read because we were having to retry the peek multiple

when peek would return less than four bytes and four bytes is the minimum we
ever get.

[SOCK] make sk_alloc use kmalloc for non performance critical families
With this we can have aggregate protocol specific struct proto_sock
allocated for non performance critical protocols.

[DECNET] Don't use sk_protinfo + private sock slab cache
DecNET already uses a private sock slab cache, but initializes
sk->sk_protinfo,
pointing to (sk + 1), this is wrong because at sk_free time we call
sk->sk_destruct, that by default points to sock_def_destruct, that does a
kfree
on sk->sk_protinfo, since it was initialized at net_proto_family->create()
time
(dn_create), but in decnet sk_protinfo was not kmalloced, it was allocated
piggybacked to struct sock.
This doesn't causes problems because decnet sets sk->sk_destruct to a custom
function that doesn't calls kfree(sk->sk_protinfo), but to reach a long time
goal of killing sk_protinfo lets just make DN_SK return sk + 1.
I left merging dn_scp with dn_sock for later, as the current state suits my
needs to introduce connection_sock.

Hi,
Description: Use msleep() instead of schedule_timeout() to guarantee the task

assignment in a pair of spots. I am still concerned about those sleeps, as
TASK_INTERRUPTIBLE() is used without any checking for signals. Hence I used
msleep() for the longer delay. Perhaps the 30 jiffy delay has not been
updated for the larger HZ values and thus could be changed to msleep(300).

kbuild: Warn when building external modules without modversions
This adds a warning when building external modules (M= or SUBDIRS=
syntax) and there is no Module.symvers in the object tree. A missing
Module.symvers is a clear sign that the kernel tree itself was never
compiled. The resulting modules will work, but no symbol version
information will be attached to kernel symbols the module uses (because
that information comes from Module.symvers), and so the module will be
more unsafe.
Futhermore the external module will not record what other modules it is
depended on.
The test works with CONFIG_MODVERSIONS enabled or disabled.

The wrong version of the parmtype patch was merged, incompletely, and
the part that got merged got broken on the way. Here are the fixes:
Move __MODULE_INFO to modparam.h: This macro is used in modparam.h;
there are users who include this header but not module.h. The latter
includes modparam.h already.
__MODULE_INFO(parmtype, name##type, #name ":" #type) does not evaluate
to __MODULE_INFO(parmtype, footype, "foo:int") as was the idea, but to
__MODULE_INFO(parmtype, fooint, "foo:int") when type is bound to int.
In more complicated cases, we get syntax erros. Re-introduce the
__MODULE_PARM_TYPE macro; this is cleaner than renaming the type parameter.
Add the parmtype definition which was dropped during the merge to to the
obsolete but still heavily used MODULE_PARM macro.

I have tested and updated a patch from Randy Dunlap that fixes missing

(1234).
The patch adds the following entries for IIDC cameras that would not be
detected otherwise:
video1394 0x0000000c 0x000000 0x000000 0x00a02d 0x000101

raw1394 0x0000000c 0x000000 0x000000 0x00a02d 0x000102
This is necessary because the IIDC consortium interpreted the 1394
specifications differently. They have been summoned by the 1394TA to
change their numbering policy so that these entries are final and will
not grow forever in number.

[PATCH] kbuild: Use -Wno-pointer-sign for gcc 4.0
Compiling an allyesconfig kernel straight with a gcc 4.0 snapshot
gives nearly 10k new warnings like:
warning: pointer targets in passing argument 5 of `cpuid' differ in
signedness
Since the sheer number of these warnings was too much even for the
most determined kernel janitors (I actually asked ;-) and I don't
think it's a very serious issue to have these mismatches I submitted
an new option to gcc to disable it. It was incorporated in gcc mainline
now.
This patch makes the kernel compilation use it. There are still
quite a lot of new warnings with 4.0 (mostly about uninitialized variables),
but the compile log looks much nicer nnow.

[PATCH] kbuild: no redundant srctree in tags file
Avoid cluttering the tags/TAGS generated file with $(srctree) in the paths
if this is not needed.
This has two advantages:
- Saving about 20M on the size of the resulting tags file (which are used
currently to store the absolute path of the file names rather than the
relative one) when KBUILD_OUTPUT is not set.
- Keeping the tags file valid when the directory is renamed.
No change is done for who does make tags O=..., if this is wanted (I would
find that incommodous and non-typical for a developer, but anyway I've not
ruined functionality in that case).

[PATCH] kbuild: skip depmod if not executable
I've cross-compiled Linux on i386-netbsdelf2.0 for
arm-linux for quite some time now and everything seems
to be working perfectly except for one minor glitch in
the build process that halts module installation
(needlessly, IMHO). Specifically, if System.map exists
$(DEPMOD) is run ("for convenience" as the comment
says in the Makefile). However, on NetBSD I don't have
$(DEPMOD) available so the command fails and make
exits with non-zero exit status. Please consider the
attached patch to add a check for $(DEPMOD) so that
missing $(DEPMOD) won't halt the whole build process.

[PATCH] smc91x: allow RX of VLAN packets
This patch allows for VLAN packets to be received. The initial patch
was from Andrew de Quincey.
While there, it also adds a test against an impossible hardware state
in theory but that happened in practice where the chip returns a
packet length of 0 which, once the status words have been substracted,
causes the transfer of data with a negative length. Flaky hardware is
probably to blame here but better guard ourselves against that than
crashing the kernel. David Brownell was the happy victim of such hw.

[PATCH] use datacs in smc91x driver
From: Ian Campbell <icampbell@arcom.com>
Below is a patch to support the second 32-bit DATACS chipselect in the
smc91x driver to transfer data. Support is enabled by adding a resource to
the platform device named 'smc91x-data32'.
My platform has a 16-bit chip select for the primary IO region and no DMA.
I found that throughput went from roughly 50mbit/s to 80mbit/s. I tested
by throwing UDP packets at it using mgen (9000 packets/second with UDP
payload of 1472 bytes is roughly 100mbit/s, I think) and counting the
packets received in 60s, I then did the same for transmitting. The
measurements are very rough but the improvement seems fairly significant to
me.
Patch was compiled for lubbock and neponset and compiled and tested on my
PXA platform.

[PATCH] ata_pci_remove_one used freed memory
Attempting to unload a serial ATA driver module gave me a kernel
memory fault. I think this problem occurs in all configurations, but
I should mention that my configuration may be slightly unusual in that
I configured my BIOS not to do IDE emulation with SATA disks, and I don't
actually have any disks plugged in.
The problem was that ata_pci_remove_one would call
scsi_host_put(ap->host), which would free the memory used to hold
host_set->ports, but host_set->ports was used later in ata_pci_remove_one.
So, the following patch reorders some of the steps in
ata_pci_remove_one and seems to eliminate the problem, at least to
the extent that I can unload and reload the module, although I do not
have a SATA disk handy for testing (I'm expecting one to arrive later
today).
The patch actually makes the code four lines shorter, although
two of those lines come from putting an assignement and variable
declaration in the same line. Since the patch is a little hard to
read, here is a description of the edit steps.
1. Moved pci_release_regions() to toward the end of the routine
to facilitate merging the loops before and after it. Also, I think that
calls that are good candidates for consolidating into the bus-level code
in the future (instead of individual drivers) are best put at the beginning
or end of the driver routines so that it is clearer if there would be
problems doing such consolidation.
2. Moved the cacluation of ioaddr into the only if-branch that
uses it.
3. Moved the call to scsi_host_put to after the code that
checks ATA_FLAG_NO_LEGACY.

I have a buggy USB HID device (APC SmartUPS) in which the designers
forgot that ReportCount is a global item. Consequently, according to the
report descriptor, several reports have multiple copies of the same
usage in each field. When you actually query the device, however, only a
single copy of the usage is returned. hid-core catches the expected vs.
actual length mismatch and fails the transfer. This effectively makes
the buggy reports inaccessible even though enough data is present to
populate one usage (which is all userspace wants anyway).
This patch changes hid-core to only warn (if debug is enabled) on such
reports rather than failing the transfer.

- PCI_SAL_EXT_ADDRESS(): cast to u64 *before* shifting; otherwise
"seg << 28" is evaluated as unsigned int (32 bits) and gets
truncated when seg > 0xf
- pci_sal_read(): validate "value" ptr as other arches do
- pci_sal_{read,write}(): return -EINVAL rather than SAL error status

PCI: Enabling device 0000:00:05.0 (0000 -> 0002)
PCI: No IRQ known for interrupt pin @ of device 0000:00:05.0. Probably
buggy MP table.
It should read "No IRQ known for interrupt pin A", but the 'pin'
variable has already been decremented (from 1 to 0), so the line:
printk(KERN_WARNING "PCI: No IRQ known for interrupt pin %c of device
%s.%s\n", 'A' + pin - 1, dev->slot_name, msg);
causes "pin @" to be output, because 'A' + 0 - 1 == '@'.

a nonzero pin.

[IPV6]: match TCP port selection behavior with ipv4
This patch makes TCP over IPV6 select ports the same way the current

and a free running counter to provide seed.
This changes the port selection semantics to match TCPv4 as well.
If the port is in use but to a different remote address, it will get
reused. It looks like the TCPv6 code was not updated when the TCPv4
code changed. Now the code in ipv4/tcp_ipv4.c and ipv6/tcp_ipv6.c are

[PATCH] sundance: attempt to address high irqs due to TX overflow
In at least some versions of Kernel 2.6 (2.6.8.1, 2.6.11-rc2)
the driver drivers/net/sundance.c creates high interrupt load
(~ 100 interrupts per second) even in case of no network traffic
at all.
It seems that some sort of TX overflow handling is misplaced
and triggers interrupts very often even in case of no data to
send. The TX overflow handling has been moved to a more
appropriate place.
While there, an off by one error of reading the TX status has
also been corrected by moving the read after the break.
Thanks to Jeroen who tested the patch (also with high workload).
Interrupts are down to normal and there are no obvious side
effects.

Change set_idle handling to use a '0' report ID, meaning all reports
instead of iterating over each individual report ID. This shouldn't

[ALSA] add 96Khz support and setting sample rate for direct SPDIF output
EMU10K1/EMU10K2 driver
This patch should add support for 96Khz 'direct SPDIF' aka 'SPDIF
Bypass' (not P16V) playback mode available on the Audigy1 and 2 and
newer SBLives (?). It lets you bypass the 48khz DSP resampling when
using the card in digital mode. It also adds 96khz analog playback
support, good for testing but less interesting because it's downsampled
to 48khz. A new mixer control 'Audigy SPDIF Output Sample Rate' is
created, you can choose 44100, 48000, or 96000. Standard SPDIF
playback, AC3 passthrough (real 96khz playback), and analog playback
(96khz is resampled to 48khz in the DSP) all work with a 16 bit,96khz
wav file. Only the last was tested due to lack of any SPDIF hardware.
This was derived mostly from the opensource.creative.com driver. All
that was needed for 96khz playback to work in analog mode was changing
the format to 8000_96000 (looks like the creative driver supports 192khz
too). And, of course this sample rate has always been supported (albeit
downsampled) because if you have 48khz samples in a soundfont the
envelope engine has to be able to pitch shift them in both directions.
I still have not been able to figure out how to get 24 bit playback to
work. This is possible, independent of the P16V, for spdif and analog
24/48 playback via the DSP. I do know how to access the full 24 bits
from the ADC from within the DSP, just not how to get it in there. For
one thing I have no idea which 24 bit format it supports. Some of them
seemed to work with JACK but produced noise.
This was generated with my multichannel patch but it applies against
ALSA CVS as well.

[PKT_SCHED]: Extended Matches API
An extended match (ematch) is a small classifiction tool not worth
writing a full classifier for. Ematches can be interconnected to form
a logic expression and get attached to classifiers to extend their
functionatlity.
The userspace part transforms the logic expressions into an array
consisting of multiple sequences of interconnected ematches separated
by markers. Precedence is implemented by a special ematch kind
referencing a sequence beyond the marker of the current sequence
causing the current position in the sequence to be pushed onto a stack
to allow the current position to be overwritten by the position
referenced in the special ematch. Matching continues in the new sequence
until a marker is reached causing the position to be restored from the
stack.

The ematch provides functionality to transform the byte order of
the chunk and/or apply a mask and understands the operands eq, lt,
and gt. Basically, it is very similiar to the u32 (e)match but tries

[IPV4]: Make loopback idev stick around.
As it is when loopback_dev loses all of its IPv4 addresses its
corresponding idev will be destroyed. Unfortunately as of last
August route.c relies on the loopback idev to kill references
to other idev objects.
The end result is that when you do ip a f dev lo, unregistering
other devices will hang until those dst objects referring to
their idev objects die of natural causes. Of course this may
never happen if the processes holding those references get
dead-locked by invoking an operation that takes the RTNL.
A simple solution is to make sure that loopback's idev sticks
around all the time.
Incidentally this also fixes the setting of some flags on the
loopback idev object as currently the code that does it won't
be called if you add the addresses to lo after bring it up.

Ok, that's a bug in PCIEPORTBUS. Best is probably to
completely remove the dependency, it doesn't make much sense
(the code has to handle the case of mmconfig not being available at

[PATCH] Fix selection of command serial numbers and pids
This patch fixes one of Christroph's fixme comments in the SCSI midlayer.
The selection of the serial number and pid for commands was done
by a global variable and not SMP safe. The race was not very
serious because it was only used for error handling, but it's
still better to fix it.
I audited all the drivers and none seemed to use them
for anything interesting, so I just made it a per host counter
protected by host lock.
(in fact they could be probably removed because they only see
to be used as a flag in exception handling and for debugging.
The patch would be unfortunately quite big because a lot
of driver printks use them)
This should be slight faster on SMP too because the cache line of
the counter won't bounce around the machine.

[netdrvr mv643xx] Remove call to msleep() while locks are held. We don't really need
to
wait for the link to come up. It was a workaround to avoid a transient
error message, "Virtual device %s asks to queue packet!\n", in
dev_queue_xmit() when called by ic_bootp_send_if(). This happens because
right after opening the network device, there is a pending PHY status
change interrupt causing the driver to call netif_stop_queue(). A half
second later, the link comes up and all is well. We could have moved
the call to msleep() to mv643xx_eth_open() to perpetuate the workaround,
but I think it's best to remove it entirely.

[MM]: Add set_pte_at() which takes 'mm' and 'addr' args.
I'm taking a slightly different approach this time around so things
are easier to integrate. Here is the first patch which builds the
infrastructure. Basically:
1) Add set_pte_at() which is set_pte() with 'mm' and 'addr' arguments
added. All generic code uses set_pte_at().
Most platforms simply get this define:
#define set_pte_at(mm,addr,ptep,pteval) set_pte(ptep,pteval)
I chose this method over simply changing all set_pte() call sites
because many platforms implement this in assembler and it would
take forever to preserve the build and stabilize things if modifying
that was necessary.
Soon, with platform maintainer's help, we can kill of set_pte() entirely.
To be honest, there are only a handful of set_pte() call sites in the
arch specific code.
Actually, in this patch ppc64 is completely set_pte() free and does not
define it.
2) pte_clear() gets 'mm' and 'addr' arguments now.
This had a cascading effect on many ptep_test_and_*() routines.
Specifically:
a) ptep_test_and_clear_{young,dirty}() now take 'vma' and 'address' args.
b) ptep_get_and_clear now take 'mm' and 'address' args.
c) ptep_mkdirty was deleted, unused by any code.
d) ptep_set_wrprotect now takes 'mm' and 'address' args.
I've tested this patch as follows:
1) compile and run tested on sparc64/SMP
2) compile tested on:
a) ppc64/SMP
b) i386 both with and without PAE enabled

input: After testing on real world hardware, it's obvious we can't trust
ACPIPnP nor PnPBIOS to properly report the existence of a keyboard
and mouse port in all cases. Some BIOSes hide the ports if no mouse
or keyboard is connected, causing trouble with eg. KVM switches.
The i8042 driver now does read-only probing first, which should
not cause any problems even if an i8042 controller really is not
present.
However, on IA64 we still need to trust ACPI, since legacy-free
hardware
is common there and invalid port accesses cause exceptions.

Here comes this patch. The new "fix_pwm_polarity" module parameter
allows one to force the it87 chip reconfiguration. This is only
supported in the case the original PWM configuration is suspected to be
bogus, and only if we think that reconfiguring the chip is safe.

[PATCH] I2C: Kill i2c_client.id (1/5)
(1/5) Stop using i2c_client.id in i2c/chips drivers (mostly hardware
monitoring drivers).
Drivers affected:
* adm1021
* adm1025
* adm1026
* adm1031
* ds1621
* fscher
* gl518sm
* isp1301_omap
* lm75

* lm90
* max1619
* pcf8574
* pcf8591
* rtc8564
* smsc47m1
* w83l785ts
The vast majority of these drivers simply defined the i2c_client id
struct member but never used it, so they are not affected at all by the
change. Exceptions are:
* lm85 and rtc8564, which would at least display the id in a debug
message when assigning it. Not really useful though, as the id was then
never used.
* adm1026, which used the assigned id in all driver messages. However,
since dev_* calls will append the bus number and client address to these
messages, the id information is redundant and can go away. Also, the
driver would allow some GPIO reprogramming on the first client only
(id=0) and removing the id doesn't allow that anymore. I would restore a
similar functionality if needed, but the ADM1026 chip is found on very
few motherboards and none of these has more than one ADM1026 chip AFAIK,
so it doesn't seem to be worth the effort.

[PATCH] I2C: Kill i2c_client.id (2/5)
(2/5) Stop using i2c_client.id in media/video drivers.
Affected drivers:
* adv7170
* adv7175
* bt819
* bt856
* bttv
* cx88
* ovcamchip
* saa5246a
* saa5249

* tda7432
* tda9840
* tda9875
* tea6415c
* tea6420
* tuner-3036
* vpx3220
Most drivers here would include the id as part of their i2c client name
(e.g. adv7170[0]). This looks more like an habit than something really
needed, so I replaced the various printf by strlcpy, which should be
slightly faster. As said earlier, clients can be differenciated thanks
to their bus id and address if needed, so I don't think that including
this information in the client name is wise anyway.
Other drivers would either set the id to -1 or to a unique value but
then never use it. These drivers are unaffected by the changes.

[PATCH] I2C: Kill i2c_client.id (3/5)

* i2c/i2c-dev
* macintosh/therm_windtunnel
* sound/oss/dmasound/dac3550a
* sound/ppc/keywest
The Acorn pcf8583 driver would give the i2c_client id the same value as
the i2c_driver id, and later test that client id (in i2c). I changed it
to test the client's driver id instead. The result is the same and the
client id is then useless and can be removed.
All other drivers here would allocate the client id to some value and
then never use it. They are unaffected by the change.

which we have no documentation.

[PATCH] I2C: Remove NULL client checks in rtc8564 driver
Several functions in your rtc8564 driver verify the non-NULLity of the

can't think of any case where these functions could possibly be called
with a NULL i2c client. As a matter of fact, I couldn't find any similar
driver doing such checks.
My attention was brought on this by Coverity's SWAT which correctly
noticed that three of these functions contain explicit or hidden
dereferences of the i2c client pointer *before* the NULL check. I guess
it wasn't a problem because the NULL case cannot happen (unless I miss
something), but this still is confusing code.
Thus I propose the following changes:

From: tom watson <lkml@tommywatson.com>
While working on a driver for z85230 based board I noticed what looks like
it could be a problem. If the interrupt handler is handling an interrupt
on port b and an interrupt comes in for port a, it seems to me that the
port b handler would be called instead of the port a handler, and possibly
hang the board until reset.
Attached is a patch to set the irq methods back to port a before attempting

[PATCH] mii: add GigE support
Add support for GigE PHYs in MII support library.
This patch allows GigE drivers to use the MII library the same way
10/100 drivers do.
Since the MII library is already used by lots of network drivers and the
GigE MII register bit definitions were reserved when many 10/100 PHYs
were designed, the new GigE registers are accessed only if a driver
specifically enables it. Existing 10/100 drivers should see no behavior
differences with this change.

This semantics is specified on the man pages of some Unices and some

[ARM PATCH] 2491/1: make ixp2000 use section mappings for on-chip registers
Patch from Lennert Buytenhek
This patch makes the ixp2000 port use section mappings for on-chip
registers. This has two advantages:
1. It saves some TLB entries.
2. It enables us to work around ixp2400 erratum #66, for which the
suggested (and only) fix involves mapping all on-chip registers
using XCB=101 instead of XCB=000.
This patch was derived from an older patch for the same erratum
(ARM patch ID 2265/1), made by Deepak Saxena.
Note that this patch does not actually constitute a workaround for
erratum #66, it merely lays the foundation for such a workaround.

1) Remove the s3c24xx_{fclk,hclk,pclk} variables, and pass
these values to the clock core on initialisation. This
removes the needless double copy, as only the timer code
uses these directly (see point 4).
Add an over-all xtal clock to the clock core
2) Add a sysdev driver to the clock code to ensure all the
s3c2440 clocks are added if an s3c2440 is present.
3) Add the new IRQs to irq.c, and initialise them if the
sysdev for the s3c2440 is present.
4) Change the timer code to request the timer clk and
use it to get the frequency.
Depends on patch 2467/1
Thanks to Guillaume Gourat for the original patches that
prompted this re-write.

[NETFILTER]: Reduce netfilter memory use on MP systems
On kernels compiled with a big NR_CPUS netfilter rules would
eat a lot of memory because all counters would be duplicated
for all NR_CPUs CPUs. With NR_CPUS=256 this would add up
to many MBs of memory.
This patch only allocates enough memory for the possible CPUs,
which is usually a much smaller number than NR_CPUS.
This allows loading of bigger rule sets on 64bit systems.
There is still a limit because someone else broke vmalloc to have a 64MB
limit on 64bit systems for single allocations, 129MB on 32bit.
It allocates an array of pages with kmalloc and kmalloc has a 128K limit.
To be fixed with a separate patch.
64bit systems were hurt worst because they tend to have big NR_CPUS
and the counters need more memory there, and the vmalloc limit is lower.
But it will raise the limits even on 32bit.
And in general it saves a lot of memory.
Tested only on a small dual CPU box.

[NETFILTER]: Fix multiple problems with TCP window tracking
The first attached patch addresses several problems in the current TCP
connection tracking in the 2.6 tree. Some of the problems was reported,
others was discovered by nfsim tests:
- tcp_sack function was not safe against nonlinear skbs
- practically arbitrary RST segments (addresses, ports assumed to be
known) could cause connection teardown in conntrack (thanks to Tim
Burress for the bugreport and patch)
- article on which the code was based falsely assumed that packets
must fit completely into the window: packets must at least overlap
(thanks to Phil Oester for the bugreport and patch)
- state table slightly changed to handle ACK packets sent by server to
late resent SYNs
- tracking reopening connections reworked
- cosmetic change: when window tracking is ignored by setting
ip_conntrack_tcp_be_liberal to nonzero, it's ignored completely from
now on

instead.
This patch should fix a problem that has been experienced on at-least one
busy NFS server, but it has not had lots of testing yet. If -mm could
provide
that .....
The rpc auth cache currently differentiates between a reference due to
being in a hash chain (signalled by CACHE_HASHED flag) and any other
reference (counted in refcnt).
This is an artificial difference due to an historical accident, and it
makes cache_put unsafe.
This patch removes the distinction so now existance in a hash chain is
counted just like any other reference. Thus a race window in cache_put is
closed.

1. Split the QP spinlock into separate send and receive locks.
The only place where we have to lock both is upon modify_qp, and
that is not on data path.
2. Avoid taking any QP locks when polling CQ.
This last part is achieved by getting rid of the cur field in
mthca_wq, and calculating the number of outstanding WQEs by
comparing the head and tail fields. head is only updated by
post, tail is only updated by poll.
In a rare case where an overrun is detected, a CQ is locked and the
overrun condition is re-tested, to avoid any potential for stale
tail values.

The randomisation range is 1 megabyte (this is bigger than the stack
randomisation since the stack randomisation only needs 16 bytes alignment

[PATCH] Move accounting function calls out of critical vm code paths
In the 2.6.11 development cycle function calls have been added to lots
of hot vm paths to do accounting. I think these should not go into the
final 2.6.1 release because these statistics can be collected in a different
way that does not require the updating of counters from frequently used
vm code paths and is consistent with the methods use elsewhere in the kernel
to obtain statistics.
These function calls are
acct_update_integrals -> Account for processes based on stime changes
update_mem_hiwater -> takes rss and total_vm hiwater marks.
acct_update_integrals is only useful to call if stime changes otherwise
it will simply return. It is therefore best to relocate the function call
to acct_update_integral into the function that updates stime which is
account_system_time and remove it from the vm code paths.
update_mem_hiwater finds the rss hiwater mark. We call that from timer
context as well. This means that processes' high-water marks are now
sampled statistically, at timer-interrupt time rather than
deterministically. This may or may not be a problem..
This means that the rss limit is not always updated if rss is increased
and thus not as accurate. But the benefit is that the rss checks do no
pollute the vm paths and that it is consistent with the rss limit check.
The following patch removes acct_update_integrals and update_mem_hiwater
from the hot vm paths.

From: Jay Lan <jlan@sgi.com>
The new "move-accounting-function-calls-out-of-critical-vm-code-paths"
patch in 2.6.11-rc3-mm2 was different from the code i tested.
In particular, it mistakenly dropped the accounting routine calls
in fs/exec.c. The calls in do_execve() are needed to properly
initialize accounting fields. Specifically, the tsk->acct_stimexpd
needs to be initialized to tsk->stime.
I have discussed this with Christoph Lameter and he gave me full
blessings to bring the calls back.

[PATCH] invalidate range of pages after direct IO write
Presently we invalidate all of a file's pages when writing to any part of
that file with direct-IO.
After a direct IO write only invalidate the pages that the write intersected.
invalidate_inode_pages2_range(mapping, pgoff start, pgoff end) is added and
called from generic_file_direct_IO().
While we're in there, invalidate_inode_pages2() was calling
unmap_mapping_range() with the wrong convention in the single page case.
It was providing the byte offset of the final page rather than the length
of the hole being unmapped. This is also fixed.
This was lightly tested with a 10k op fsx run with O_DIRECT on a 16MB file
in ext3 on a junky old IDE drive. Totaling vmstat columns of blocks read
and written during the runs shows that read traffic drops significantly.
The run time seems to have gone down a little.
Two runs before the patch gave the following user/real/sys times and total
blocks in and out:
0m28.029s 0m20.093s 0m3.166s 16673 125107
0m27.949s 0m20.068s 0m3.227s 18426 126094

Replacing the spinlock with a multi-reader lock fixes this problem,
without unduly affecting anything else.
Here are the benchmark results (jobs per minute at a 50-client level,

I'm not sure what's happening in the 4-processor case. The important thing
to
note is that with a spinlock, the benchmark shows worse performance for a
12
than for an 8-way box; with the patch, the 12 way performs better, as
expected. We've done some runs with 16-way as well; without the patch
below,
the 16-way performs worse than the 12-way.
It's a tricky tradeoff, but large-smp is hurt a lot more by the spinlocks
than
small-smp is by the rwlocks. And I don't think we really want to implement
compile-time either-or-locks.

[PATCH] ppc32: Don't create .tmp_gas_check
This changes how the ppc32 'checkbin' target works. Previously we did all
of the tests using variables which would be evaluated for any and every
make target. This meant that 'make tags' for example would leave behind a
'.tmp_gas_check' file even though we didn't actually compile up anything,
and would get in the way of diffs. By moving all of this logic directly
into the 'checkbin' target, we only test gcc/gas versions when we're going
to compile.

[PATCH] ppc64: collect and export low-level cpu usage statistics
POWER5 machines have a per-hardware-thread register which counts at a rate
which is proportional to the percentage of cycles on which the cpu
dispatches an instruction for this thread (if the thread gets all the
dispatch cycles it counts at the same rate as the timebase register). This
register is also context-switched by the hypervisor. Thus it gives a
fine-grained measure of the actual cpu usage by the thread over time.
This patch adds code to read this register every timer interrupt and on
every context switch. The total over all virtual processors is available
through the existing /proc/ppc64/lparcfg file, giving a way to measure the
total cpu usage over the whole partition.

[PATCH] ppc64: Implement a vDSO and use it for signal trampoline
This patch adds to the ppc64 kernel a virtual .so (vDSO) that is mapped
into every process space, similar to the x86 vsyscall page. However, the
implementation is very different (and doesn't use the gate area mecanism).
Actually, it contains two implementations, a 32 bits and a 64 bits one.
These vDSO's are currently mapped at 0x100000 (+1Mb) when possible (when a
process load section isn't already there). In the future, we can randomize
that address, or even imagine having a special phdr entry letting apps that
wnat finer control over their address space to put it elsewhere (or not at
all).
The implementation adds a hook to binfmt_elf to let the architecture add a
real VMA to the process space instead of using the gate area mecanism.
This mecanism wasn't very suitable for ppc, we couldn't just "shove" PTE
entries mapping kernel addresses into userland without expensive changes to
our hash table management. Instead, I made the vDSO be a normal VMA which,
additionally, means it supports copy-on-write semantics if made writable
via ptrace/mprotect, thus allowing breakpoints in the vDSO code.
The current implementation of the vDSOs contain the signal trampolines with
appropriate DWARF informations, which enable us to use non-executable
stacks (patches to come later) along with a few more functions that we hope
glibc will soon make good use of (this is the "hard" part now :) Note that
the symbols exposed by the vDSO aren't "normal" function symbols, apps
can't be expected to link against them directly, the vDSO's are both seen
as if they were linked at 0 and the symbols just contain offsets to the
various functions. This is done on purpose to avoid a relocation step
(ppc64 functions normally have descriptors with abs addresses in them).
When glibc uses those functions, it's expected to use it's own trampolines
that know how to reach them.
In some cases, the vDSO contains several versions of a given function (for
various CPUs), the kernel will "patch" the symbol table at boot to make it
point to the appropriate one transparently. What is currently implemented
is:
- int __kernel_gettimeofday(struct timeval *tv, struct timezone *tz);
This is a fully userland implementation of gettimeofday, with no barriers
and no locks, and providing 100% equivalent results to the syscall version
- void __kernel_sync_dicache(unsigned long start, unsigned long end)
This function sync's the data and instruction caches (for making data
executable), it is expected that userland loaders use this instead of
doing it themselves, as the kernel will provide optimized versions for the
current CPU. Currently, the vDSO procides a full one for all CPUs prior
to POWER5 and a nop one for POWER5 which implements hardware snooping at
the L1 level. In the future, an intermediate implementation may be done
for the POWER4 and 970 which don't need the "dcbst" loop (the L1D cache is
write-through on those).
- void *__kernel_get_syscall_map(unsigned int *syscall_count);
Returns a pointer to a map of implemented syscalls on the currently
running kernel. The map is agnostic to the size of "long", unlike kernel
bitops, it stores bits from top to bottom so that memory actually contains
a linear bitmap check for syscall N by testing bit (0x80000000 >> (N &
0x1f)) of * 32 bits int at N >> 5.
Note about backward compatibility issues: A bug in the ppc64 libgcc
unwinder makes it unable to unwind stacks properly accross signals if the
signal trampoline isn't on the stack. This has been fixed in CVS for gcc
4.0 and will be soon on the stable branch, but the problem exist will all
currently used versions.
That means that until glibc gets the patch to enable it's use of the vDSO
symbols for the DWARF unwinder (rather trivial patch that will be pushed to
glibc CVS soon hopefully), unwinding from a signal handler will not work
for 64 bits applications.
I consider this as a non-issue though as a patch is about to be produced,
which can easily get pushed to "live" distros like debian, gentoo, fedora,
etc... soon enough (it breaks compatilbity with kernels below 2.4.20
unfortunately as our signal stack layout changed, crap crap crap), as there
are few 64 bits applications out there (expect gentoo), as it's only really
an issue with C++ code relying on throwing exceptions out of signal
handlers (extremely rare it seems), and as "release" distros like SLES or
RHEL will probably have the vDSO enabled glibc _and_ the unwinder fix by
the time they release a version with a 2.6.11 or 2.6.12 kernel anyway :)
So far, I yet have to see an app failing because of that...
Finally, many many many thanks to Alan Modra for writing the DWARF
information of the signal handlers and debugging the libgcc issues !

[PATCH] ppc64: functions to reserve performance monitor hardware
The PPC64 interrupt code includes a hook to call when an exception
from the performance monitor unit occurs. However, there's no way of
reserving the hook properly, so if more than one bit of code tries to
use it things will get ugly. Currently oprofile is the only user, but
there are likely to be more in future e.g. perfctr, if and when it
reaches a fit state for merging.
This patch creates functions to reserve and release the performance
monitor hardware (including its interrupt), and makes oprofile use
them. It also creates a new arch/ppc64/kernel/pmc.c, in which we can
put any future helper functions for handling the performance monitor
counters.

[PATCH] Consolidate compat_sys_waitid
This patch does:
- consolidate the three implementations of compat_sys_waitid
(some were called sys32_waitid).
- adds sys_waitid syscall to ppc
- adds sys_waitid and compat_sys_waitid syscalls to ppc64
I have left PARISC and MIPS to their own devices (by request).

There was a lot of fun in laying the foundations. Now it's time

This patch fixes the calculations in xfrm[46]_output so that we don't
reject properly sized packets from the TCP stack. The previous
calculation is wrong because the xfrm overhead is not constant.

[IPSEC]: Fix xfrm[46]_update_pmtu to update top dst
Let's also fix IPsec PMTU storage. When we get an MTU update for an
xfrm_dst, it should be done to the top dst, not the bottom dst.
For example, when we get a need-to-frag message for host C behind
a our IPsec peer B, we should be updating the dst entry for C and
not B as we do now.
I've removed the boundary checks since the same checks are done
in ipv[46]/route.c already.

[PATCH] NCR5380 delayed work fix and locking fix
Changes to the NCR5380 driver between 2.6.9 and 2.6.10 replaced the
driver's home-grown delayed work implementation with a call to
schedule_delayed_work(). However, the delay argument was not passed
correctly, so the work was usually scheduled for _way_ too far in
the future. This patch fixes this.
NCR5380_print_status() is called from NCR5380_abort() and from
NCR5380_bus_reset(). In at least the abort() case, the host lock
has already been acquired by scsi_error.c:scsi_try_to_abort_command().
NCR5380_print_status() calls NCR5380_proc_info() which also acquires
and releases the host lock. This patch removes the call to
NCR5380_proc_info() from NCR5380_print_status.
Cosmetic: Remove duplicated lines of code from NCR5380_abort().

[PATCH] Display SPI transfer agreement in common code
[ This is an updated version of
http://marc.theaimsgroup.com/?l=linux-scsi&m=11091830...
Relative to that patch, it prints the period in a nicer way; exactly
the same way as the strings in the original version of this file. ]
Introduce a generic SPI function to print the negotiated transfer
agreement. It's based on the implementation in sym53c8xx_2/sym_misc.c.
I have changes in my tree to make 53c700, ncr53c8xx and sym2 use it.
Other drivers need to be converted to use the SPI transport layer first.
In order to calculate the speed I needed to be able to convert from
period factor to period in picoseconds. That required changing
(show|store)_spi_transport_period to work in picoseconds rather than
a string.

Here's the patch to fix those two problems. Yes I know

[PATCH] USB Storage: devices which don't process PREVENT-ALLOW MEDIUM REMOVAL
This patch started life as as423, and has been re-generated against the
current tip.
Some storage devices don't like PREVENT-ALLOW MEDIUM REMOVAL commands;
rather than returning an Invalid Command ASC they just die or imagine that
the medium has actually been removed. Until now people have been relying
on the SCSI blacklist table, which can be updated at runtime, to mark
devices which shouldn't receive these commands. However it will be more
efficient and easier to do it from within usb-storage, particularly since
many of these devices share the same USB Vendor and Product IDs (while
having different INQUIRY product strings).
*sigh* We really should be trying to push as much of this as possible onto
hotplug. It's easier to update userspace tools than the kernel to support
a new device.
The relevant devices already have unusual_devs entries; this patch just
adds the new flag to those entries and uses it to set a corresponding flag
in the scsi_device structure.

[PATCH] USB: add 'distrust_firmware' option to ohci
This replaces an undocumented/experimental "power_switching" flag with a
more useful one that lets the driver rely on the boot firmware to report

The driver still defaults to munging those informational flags (as it has
since 2.2!), so usbcore usually won't try to power-switch with OHCI, but
now we have a simple way to default to the behavior specified by the board
manufacturer.
Also corrects a misprint in the debug 'registers' dump: a bit was shifted
right by one nibble, so every controller was reported as supporting the

[PATCH] USB: Initialize connected ports on newly-activated hubs
This patch changes the mechanism used for detecting devices that were
already connected to a hub at the time the hub was activated. This can
occur in several different circumstances:
when the hub is configured for the first time,
when the hub is reset following a malfunction,
when the hub is resumed.
The patch mainly addresses the third possibility, although it also handles
the other two. The scenario I have in mind is waking up from a system
suspend, where the user has plugged in a new USB device while the system
was asleep, and for some reason the hub no longer has a record of the
connect change on that port. (Maybe the BIOS or the boot kernel has
interfered.) At any rate, the patch causes the hub driver to scan all
ports in the reactivated hub, and if it finds a connected port with no
child device already allocated then it pretends there was a connect-change
event on that port.
This will serve to take care of ports with new devices attached that the
driver doesn't know about. The existing resume code already handles the
case of ports that used to have a device but don't any longer. The
remaining case, where different devices are attached to the port before
suspending and after resuming, still needs to be handled. The resume code
should call the same "descriptors changed" check used by usb_reset_device.
That's a patch for another day.

[PATCH] USB: add usbmon, a USB monitoring framework
This patch adds so-called "usbmon", or USB monitoring framework, similar
to what tcpdump provides for Ethernet. This is an initial version, but
it should be safe and useful. It adds an overhead of an if () statement
into submission and giveback paths even when not monitoring, but this
was deemed a lesser evil than stealth manipulation of function pointers.
The patch makes two changes to hcd.c which make usbmon more useful:
- Change the way we determine that DMA should not be mapped for root
hubs, so that usbmon knows easily when it's safe to capture data.
- Return exports of usb_bus_list and usb_bus_list_lock for those who
wish to build usbmon as a module.
This version of the patch changes #define to inlines for hooks and
drops extra mod_ops.

Directly use wait-queues to remove remaining callers of
interruptible_sleep_on_timeout(). Signals are not checked (except in one
case) in the current code, so interruptible should not be necessary.
Modify the wake_up*() calls to match the wait-queue usage. There were
some naming conflicts, which I tried to resolve appropriately. The final
replacement is within a #if 0 / #endif section of code, but in case that
code is ever used again, I would prefer it had the correct interface :)

[PATCH] USB: don't power down net2280 on suspend
This creates a module parameter "enable_suspend", and changes the default
behavior to avoid the need to power cycle machines with net2280 cards to
recover from some common developer actions (like rmmod/modprobe).
When set to 1, the net2280, for better or worse, will enter low-power
mode when the USB host requests it. This is fine except in situations
involving a power-cycling host or rmmoding the gadget driver while
connected to a suspended (or disconnected!) port.
When set to 0 (now the default), the driver will report suspend requests
to the gadget driver, but will not place the NET2280 into low-power mode.
This works fine in all situations except bus-powered devices (for which
a PCI+Linux-based NET2280 generally doesn't make much sense anyway)
It also (finally...) updates NetChip references to refer to PLX; and
updates the dates on the driver.

[PATCH] USB: ethernet gadget driver aligns IP headers
Align incoming Ethernet packets so the header after Ethernet starts on
something closer to a cacheline boundary. This normally just tweaks
performance for the IP layer. But on one board (a no-MMU ARM9TDMI with
no hardware support for alignment fixups) it's needed to prevent the
IP checksumming code from failing.

[PATCH] USB: ehci updates for TDI/ATG silicon
This patch updates support for the TDI EHCI controller, which is mostly

- Correctly initialize the latest chip, which has both host (EHCI)
and peripheral modes.
- Initialize split isochronous transfers to use the integrated TT.
Most of the patch, by volume, just changes the company name from ARC to TDI
in
the source code; TransDimension bought ARC's peripheral connectivity
business.

Go back to aligning RX packets to make the IP layer happy, now that

platforms don't seem to behave; so it may have correctness impacts too.

[PATCH] USB: Clear endpoint toggles in usb_set_interface
Pete Zaitcev has found some USB devices that don't reset their endpoint
data toggles when they get a SET-INTERFACE request. Apparently they
interpret the USB specification too literally when it says that the
toggles must be reset whenever the alternate setting is "changed".
Anyway, this patch calls usb_clear_halt for all endpoints in the
altsetting whenever usb_set_interface is called and the new altsetting is
the same as the old one. It adds some extra overhead for the majority of
devices that don't need it, but fortunately usb_set_interface isn't called
very often.

It turns out that patch as460 is all right as it stands, and the addition
of the patch below will resolve the problem. It prevents the OHCI drivers
from returning IRQ_NONE on architectures that use edge-triggered
interrupts. The patch has been OK'ed by Christopher and David. Just be
sure to apply this one and as460 at the same time!
Properly speaking this problem ought to be fixed in the interrupt core
since it affects every driver, not just USB. Until that happens, this
will suffice.

[PATCH] vm: pageout throttling
With silly pageout testcases it is possible to place huge amounts of memory
under I/O. With a large request queue (CFQ uses 8192 requests) it is
possible to place _all_ memory under I/O at the same time.
This means that all memory is pinned and unreclaimable and the VM gets
upset and goes oom.
The patch limits the amount of memory which is under pageout writeout to be
a little more than the amount of memory at which balance_dirty_pages()
callers will synchronously throttle.
This means that heavy pageout activity can starve heavy writeback activity
completely, but heavy writeback activity will not cause starvation of
pageout. Because we don't want a simple `dd' to be causing excessive
latencies in page reclaim.

[PATCH] stop using "base" argument in __free_pages_bulk()
Appended is a patch which stops using the zone->zone_mem_map to calculate
the buddy and combined page pointers. It uses the fact that the mem_map
array is guaranteed to be contigious for the surrounding (1 << MAX_ORDER)
pages. The relative positions of the pages in the physical address space
to provide the alignement; which conicidentally fixes the issue where zones
are not aligned at MAX_ORDER. There is a very comprehensive comment in the
new code explaining the mathematical relationship between a page and its
buddy so I won't reproduce it here.
This kind of approach is required for CONFIG_NONLINEAR systems where the
mem_map is not contiguous within a zone, and the zone->zone_mem_map is not
used at all.
This patch has been boot-tested on a large variety of systems and
architectures: my P4 laptop, 16-way NUMAQ, 16-way Summit, 4-way x86 SMP,
ppc64 LPAR, x86_64, and several ia64 configurations.
It has been performance-tested on a 16-way NUMAQ. SDET shows a very slight
(within margin of error) performance gain. Kernbench shows an
approximately ~1% decrease in system time with this patch applied. So, it
has a likely positive performance impact.
However, the patch has the potential to have a negative performance impact
on systems with an expensive page_to_pfn() implementation. But, I think
the NUMAQ has one of the more expensive ones around, and it doesn't seem
mind too much.

[PATCH] Fix mincore cornercases: overflow caused by large "len"
This patch fixes 2 cornercases of overflow caused by argument len in
sys_mincore():
Case 1: len is so large that will overflow to 0 after page alignment.
E.g. len=(size_t)(-1), i.e. 0xff...ff.
Expected result: it's overflow and return ENOMEM.
Current result: len is aligned to 0, then treated the same as len=0 and
return succeed.
This cornercase has been fixed in do_mmap_pgoff(), and here
sys_mincore() also needs this fix.
Case 2: len is a large number but will not overflow after alignment. But
start+len will overflow.
E.g. len=(size_t)(-PAGE_SIZE), and start>0.
Expected result: it's overflow and return ENOMEM.
Current result: return EINVAL. Looks like considering len as a
non-positive value, probably influenced by manpage. But since the type
of len is size_t, i.e. unsigned, it shouldn't be considered as
non-positive value.
I've also reported this inconsistency to manpage mincore.

[PATCH] readahead: simplify ra->size testing
Currently page_cache_readahead() treats ra->size == 0 (first read)
and ra->size == -1 (ra_off was called) separately, but does exactly
the same in both cases.
With this patch we may assume that the reading starts in 'ra_off()'
state, so we don't need to consider the first read as a special case.
file_ra_state_init() sets
ra->prev_page = -1;
ra->size = 0;
When the page_cache_readahead() is called for the first time it sets
ra->size to nonzero value either via get_init_ra_size() or ra_off().
So ra->size == 0 implies that ra->prev_page == -1. I am ignoring the
case when readahead is disabled via ra->ra_pages == 0.
page_cache_readahead detects sub-page sized reads:
if (offset == ra->prev_page && req_size == 1 && ra->size != 0)
But if offset == ra->prev_page, then ra->size == 0 can happen only if
offset == -1, so there is no need to check ra->size here. If application
starts reading 16Tb file from the last page then readahead can't help.
First offset==0 read or first sequential detection:
if ((ra->size == 0 && offset == 0) || (ra->size == -1 && sequential)
could be changed to:
if ((ra->size == 0 && sequential) || (ra->size == -1 && sequential)
which means:
if (sequential && (ra->size == 0 || ra->size == -1))
Random case detection:
if (!sequential || (ra->size == 0))
But if sequential == 1, then ra->size can't be 0, this case is already
handled
before.
Now we have:
if (offset == ra->prev_page && req_size == 1)
/* sub-page reads */
if (sequential && (ra->size == 0 || ra->size == -1))
/* first offset==0 read or first sequential */
if (!sequential)
/* random case */
Now ->size is checked only in one place, so ra_off() can set ra->size = 0,
and we can just test ->size against 0.

[PATCH] readahead: improve sequential read detection
1. Current code can't always detect sequential reading, in case
when read size is not PAGE_CACHE_SIZE aligned.
If application reads the file by 4096+512 chunks, we have:
1st read: first read detected, prev_page = 2.
2nd read: offset == 2, the read is considered random.
page_cache_readahead() should treat prev_page == offset as
sequential access. In this case it is better to ++offset,
because of blockable_page_cache_readahead(offset, size).
2. If application reads 4096 bytes with *ppos == 512, we have to
read 2 pages, but req_size == 1 in do_generic_mapping_read().
Usually it's not a problem. But in random read case it results
in unnecessary page cache misses.

[PATCH] Bad page state mapcount
A small change to the tests for "Bad page state", to avoid one class of the
page_remove_rmap BUG reports, giving more information while letting the
system continue: check page_mapcount (_mapcount != -1) rather than
page_mapped (_mapcount >= 0).
And how does _mapcount go bad? In the case under study, it looks sure now
that an overheating(?) Pentium III sometimes gets confused by a pair of
instructions in the no-buddy-bitmap __free_pages_bulk, and clears the
PG_private bit from the _mapcount field while buddying around - changing
PG_private value changes the bit cleared from _mapcount. Bad page state
mapcount:-4096 would have tracked this down much sooner, and will be
recognizable if other cpus show the same aberrant reaction to 2.6.11.
The page_remove_rmap BUG does need to be replaced by more permissive and
informative handling, but I'm not yet ready to to finalize such a patch.
Please admit Colin Harrison to the Order of the Iridescent Penguin, for his
tireless testing.

[PATCH] Speed freeing memory for suspend.
Here's a patch I've prepared which improves the speed at which memory is
freed
prior to suspend. It should be a big gain for swsusp. For suspend2, it
isn't
used much, but has shown big improvements when I set a very low image size
limit and had memory quite full.
1GB P4, 2.6.11+Suspend2 2.1.8.
Soft image size limit set to 2MB to emulate Pavel's implementation (eat
as much memory as we can).
Without patch:
Freed 16545 pages in 4000 jiffies = 16.16 MB/s
Freed 83281 pages in 14060 jiffies = 23.14 MB/s
Freed 237754 pages in 41482 jiffies = 22.39 MB/s
With patch:
Freed 52257 pages in 6700 jiffies = 30.46 MB/s
Freed 105693 pages in 11035 jiffies = 37.41 MB/s
Freed 239007 pages in 18284 jiffies = 51.06 MB/s
With a less aggressive image size limit (200MB):
Without the patch:
Freed 14600 pages in 1749 jiffies = 32.61 MB/s (Anomolous!)
Freed 88563 pages in 14719 jiffies = 23.50 MB/s
Freed 205734 pages in 32389 jiffies = 24.81 MB/s
With the patch:
Freed 68252 pages in 496 jiffies = 537.52 MB/s
Freed 116464 pages in 569 jiffies = 798.54 MB/s
Freed 209699 pages in 705 jiffies = 1161.89 MB/s
The later pages take more work to get, which accounts for the slower MB/s
with
smaller numbers of pages to free. Without the patch, though, getting the
easier pages also takes longer because we do a far greater number of
invocations of shrink_all_memory in order to get the same number of pages.

[PATCH] sh64: Initial checkstack port
This provides a port of checkstack for sh64 for the simple frames
allocated as an immediate with a single instruction.
Stack frame creation on sh64 happens in a couple of different ways,
when the frame size is less than 511 bytes an addi or addi.l is
typically used, generally along the lines of something like:
addi{,.l} r15, -IMM_FRAME_SIZE, r15
For larger frames, this ends up getting split up into a
movi/sub pair:
movi IMM_FRAME_SIZE, rX
sub r15, rX, r15
We currently don't handle the split pair case, as basically
any register can be used, and there is no easy way to determine
what happens without scanning the prologue multiple times and
using some sort of register cache (we already do something
similar for the sh64 stack unwinder, but it would be preferable
not to do this in perl..).
This does have limited usefulness in that we are not easily able
to check for huge frames without manual inspection, but this is
still useful enough in the general case to be worth doing for
the addi/addi.l case as long as people are aware of this caveat.
It may be worth revisiting at a later point to try and catch the
larger users though.

[PATCH] Allow hot-add enabled i386 NUMA box to boot
Dave Hanson mentioned I should send this patch to you. I posted it to
linux-mm a while ago without complaint. This patch solves a simple
problem related to the interpretation on the SRAT table and the info
found in the e820.
When a possible hot-add area is exposed on my box (IBM x445 with hot
add enabled in the bios) my SRAT table correctly exposed a new node from
the end of my physical memory to 64gb. In the present kernels the numa
KVA areas (based on the SRAT) are calculated before find_max_pfn. The
remap area is created for this large non-populated zone and the system
dies a while later during bootup.
I believe the correct things to do (as did the hot-plug community) the
correct thing to do is the keep the node_start_end_pfn data structures
focuses on memory that is in the system. That is all this patch does.
It ignores any node data (correctly reported by the SRAT) that is above
the e820 end of memory.

[PATCH] remove dead cyrix/centaur mtrr init code
There are several cases where __init function pointers are stored in a
general purpose struct. For example, a SCSI template may contain a __init
detect function. Have not yet thought of an elegant way to avoid this.
One such case is the mtrr code, where struct mtrr_ops has an init field
pointing at __init functions. Unless I overlook something, this case may
be easy to settle, since the .init field is never used.
The patch below comments out the declaration and initialisation of the
.init field of struct mtrr_ops, and puts #if 0 ... #endif around the
centaur_mcr_init() and cyrix_arr_init() code.
Simultaneously a number of variables are made static.

The NMI code indiscriminatly sets index registers and values in the same
place the CMOS clock is set. If you are setting the CMOS clock and an NMI
occurs, Bad values could be written to or read from the CMOS RAM, or the
NMI operation might not occur correctly.
Fixing this requires creating a special lock so the NMI code can know its
CPU owns the lock an "do the right thing" in that case.

This is a resend of a patch that has been applied to 2.4. The low power
codec functionality has also now been included in ALSA.
It checks the codec ID before doing an AC97 register reset. This allows
the kernel to support low power codecs that are powered down by a reset
command. This patch also fixes some other minor issues.
Changes:-
- Added AC97_DEFAULT_POWER_OFF to ac97_codec_ids[]
- ac97_probe now checks hardwired codec ID's before sending a reset
- Added support for WM9713
- Moved the codec specific inits after the mixer setup as some init
- tings were being clobbered.
- Added extra check so that default_digital_ops doesn't overwrite a valid
codec_ops. (SPDIF)

[PATCH] Fix kallsyms/insmod/rmmod race
The attached patch fixes a race between kallsyms and insmod/rmmod.
The problem is this:
(1) The various kallsyms functions poke around in the module list without
any
locking so that they can be called from the oops handler.
(2) Although insmod and rmmod use locks to exclude each other, these have no
effect on the kallsyms function.
(3) Although rmmod modifies the module state with the machine "stopped", it
hasn't removed the metadata from the module metadata list, meaning that
as soon as the machine is "restarted", the metadata can be observed by
kallsyms.
It's not possible to say that an item in that list should be ignored if
it's state is marked as inactive - you can't get at the state
information
because you can't trust the metadata in which it is embedded.
Furthermore, list linkage information is embedded in the metadata too,
so
you can't trust that either...
(4) kallsyms may be walking the module list without a lock whilst either
insmod or rmmod are busy changing it. insmod probably isn't a problem
since nothing is going a way, but rmmod is as it's deleting an entry.
(5) Therefore nothing that uses these functions can in any way trust any
pointers to "static" data (such as module symbol names or module names)
that are returned.
(6) On ppc64 the problems are exacerbated since the hypervisor may
reschedule
bits of the kernel, making operations that appear adjacent occur a long
time apart.
This patch fixes the race by only linking/unlinking modules into/from the
master module list with the machine in the "stopped" state. This means that
any "static" information can be trusted as far as the next kernel reschedule
on any given CPU without the need to hold any locks.
However, I'm not sure how this is affected by preemption. I suspect more work
may need to be done in that case, but I'm not entirely sure.
This also means that rmmod has to bump the machine into the stopped state
twice... but since that shouldn't be a common operation, I don't think that's
a problem.
I've amended this patch to not get spinlocks whilst in the machine locked
state - there's no point as nothing else can be holding spinlocks.

[PATCH] sys_setpriority() euid semantics fix
What _is_ inconsistent is kernel/sys.c's setpriority()/set_one_prio().
It checks current->euid|uid against p->uid, which makes little sense, but
is how we've been doing it ever since. It's a Linux quirk documented in
the manpage. To make things funnier, SuS requires current->euid|uid match
against p->euid.
The patch below fixes it (and brings the logic in line with what
setscheduler()/setaffinity() does), but if we do it then it should be done
only in 2.6.12 or later, after good exposure in -mm.
(Worst-case this could break an application but i highly doubt it: it at
most could deny renicing another task to positive (or in very rare cases,
to negative) nice values, which no application should crash on something
like that, normally.)

[PATCH] minor conceptual fix for /proc/kcore header size
While investigating the 2.4 memory corruption problem fixed by the patch
previously posted, it was noticed that the 2.6 version of get_kcore_size()
inappropriately uses sizeof(struct memelfnote) in its calculation of the
/proc/kcore ELF header size. What is actually stored in the header is an
"elf_note" structure plus the 4 ASCII chars "CORE".
It just so happens that on 32-bit arches, both calculations result in the
same value (16). But on 64-bit arches, the allocated size (24) is larger
than necessary (16). This does not result in any possible data corruption,
but it might be nice to correct this "conceptual" error.

[PATCH] clean up and unify asm-*/resource.h files
This patch does the final consolidation of asm-*/resource.h file, without
changing any of the rlimit definitions on any architecture. Primarily it
removes the __ARCH_RLIMIT_ORDER method and replaces it with a more compact
and isolated one that allows architectures to define only the offending
rlimits.
This method has the positive effect that adding a new rlimit can now be
purely done via changing asm-generic/resource.h alone. Previously one
would have to patch 4 other (sparc, sparc64, alpha and mips) resource.h
files.
The patch also does style unification, whitespace cleanups and
simplification of resource.h files and cleans up the asm-generic/resource.h
file as well. I've added more comments too.
This patch should have no effect on any code on any architecture. (i.e.
it's a pure identity patch.)
Tested on x86 and carefully reviewed to make sure that Sparc, Sparc64,
MIPS and Alpha rlimits are still the same as required by the ABI.

[PATCH] add local bio pool support and modify dm
I've had this patch reviewed by Jens, and incorporated his recommended
fixes.
The patch adds new interfaces to bio.c that support the creation of local
bio and bvec pools. This is important for layered drivers that need to
allocate new bio and bvec structures in response to bio's submitted to it
from higher up. The layered drivers can allocate local pools of bio
structures to preclude deadlock under global bio pool exhaustion.
The device mapper source files have been modified to remove duplicate bio
code, and to use the new interfaces to create local bio pools.
From: Dave Olien <dmo@osdl.org>
Change bio_clone() to use the global bio_set pool instead of the bio_set pool
associated with the bio argument. This is because raid5 and raid6 bio's are
not allocated from a bio_set and have no bio_set associated with them. This
patch along with the patch Linux just accepted allows raid5 and raid6 to
function.

[PATCH] a_ops-based loop I/O
Implements fallback to file_operations->write in the case that
aops->{prepare,commit}_write are not present on the backing filesystem.
The fallback happens in two different ways:
- For normal loop devices, i.e. ones which do not do transformation on
the data but simply pass it along, we simply call fops->write. This
should be pretty much just as fast as using aops->{prepare,commit}_write
directly.
- For all other loop devices (e.g. xor and cryptoloop), i.e. all the
ones which may be doing transformations on the data, we allocate and map
a page (once for each bio), then for each bio vec we copy the bio vec
page data to our mapped page, apply the loop transformation, and use
fops->write to write out the transformed data from our page. Once all
bio vecs from the bio are done, we unmap and free the page.
This approach is the absolute minimum of overhead I could come up with and
for performance hungry people, as you can see I left the address space
operations method in place for filesystems which implement
aops->{prepare,commit}_write.
I have tested this patch with normal loop devices using
aops->{prepare,commit}_write on the backing filesystem, with normal loop
devices using the fops->write code path and with cryptoloop devices using
the double buffering + fops->write code path.

[PATCH] add timing information to printk messages
Here's a little patch which is useful for showing timing information for
kernel bootup activities.
This patch adds a new Kconfig option under "Kernel Hacking" and a new
option for the kernel command line. It also provides a script for showing
delta information.
Note that the timing data may not be correct on some platforms until after
time_init() is called.
Recently (as of about 2.6.10) I found that the message log produced by
dmesg is truncated when I use this feature. That is, the first few printk
messages of the boot sequence are not in the dmesg output, although they
are printed to console during startup. This is a new behavior - dmesg
output was fine as of 2.6.9. Increasing CONFIG_LOG_BUF_SHIFT had no effect
on the truncation.
Has something changed with printk recently?

[PATCH] remove mount option parsing from procfs
This patch removes the mount options of the proc filesystem. They don't
have any effect since 2.4.something.
Only proc_fill_super() calls parse_options, notably proc_remount() does
not. And proc_fill_super() is only called at the very first mount which in
turn is the one caused by kern_mount() in fs/proc/root.c and that passes a
NULL pointer as mount options string. It is called only once because proc
is a filesystem with a single super_block (i.e. it uses get_sb_single()).
Since noone seems to miss the uid and gid options so far I suggest to
simply remove them. Their function can be easily performed in userspace.
E.g. this (if it worked like intended):
# mount -t proc -o uid=procuser,gid=procgrp proc /proc
can be done like so, probably in some init script:
# mount -t proc proc /proc && chown procuser:procgrp /proc
But I don't see why anyone would want to do that in the first place.

[PATCH] partitions/msdos.c fix
A well-known kernel bug is that it guesses at the partition type and the
partitions on any disk it encounters. This is bad because needless I/O is
done, slowing down the boot, sometimes quite a lot, especially when I/O
errors occur. And it is bad because sometimes we guess wrong.
In other words, we need the user space command `partition', where
"partition -t dos /dev/sda" reads a DOS-type partition table. (And
"partition /dev/sda" tries all known heuristics to decide what type of
partitioning might be present.) The two variants are: (i) partition tells
the kernel to do the partition table reading, and (ii) partition uses partx
to read the partition table and tells the kernel one-by-one about the
partitions found this way.
Since this is a fundamental change, a long transition period is needed, and
that period could start with a kernel boot parameter telling the kernel not
to do partition table parsing on a particular disk, or a particular type of
disks, or all disks.
This could have been the intro to a patch doing that, but is not. (It is
just an RFC.)
The tiny patch below prompted the above - it was suggested by Uwe Bonnes
who encountered USB devices without partition table where our present
heuristics did not suffice to stop partition table parsing. It causes the
kernel to ignore partitions of type 0. A band-aid.
I think nobody uses such partitions seriously, but nevertheless this should
probably live in -mm for a while to see if anybody complains.

idle loop code because it's always checking whether its cpu has gone
offline. Replacing every use of smp_processor_id with _smp_processor_id in
all idle loop code is one solution; another way is explicitly binding idle
threads to their cpus (the smp_processor_id warning does not fire if the
caller is bound only to the calling cpu). This has the (admittedly slight)
advantage of letting us know if an idle thread ever runs on the wrong cpu.

if (!name)
return -ENOMEM;
...
if ( !wq ) {

wq = kmalloc(sizeof(struct autofs_wait_queue), GFP_KERNEL);

return -ENOMEM;
}
...
wq->name = name;
...
} else {
atomic_inc(&wq->wait_ctr);
up(&sbi->wq_sem);
...
}
In the else clause, we forget to free the name we kmalloc'd above. This is
pretty easy to trigger with the following reproducer:
setup an automount map as follows:
for n in `seq 1 48`; do echo "$n server:/export/$n" >> /etc/auto.test; done
setup a master map entry to point at this:
echo "/test /etc/auto.test --timeout=1" >> /etc/auto.master
Now, assuming the nfs server was setup to export said directories, run the
following shell script in two xterms:
#!/bin/sh
while true; do
for n in `seq 1 48`; do
ls /test/$n
done
sleep 2
done
and watch the size-256 slab cache grow

atm/ambassador: fix text section references to __init text and __initdata;
The biggest negative about this AFAIK is that it makes ucode_data
non-initdata, and that moves about 8 KB of data from .init.data
to .data. Similarly, .text increases by approx. 1300 bytes (on x86-32).

[PATCH] base-small: introduce the CONFIG_BASE_SMALL flag
This patch series introduced a new pair of CONFIG_EMBEDDED options call
CONFIG_BASE_FULL/CONFIG_BASE_SMALL. Disabling CONFIG_BASE_FULL sets the
boolean CONFIG_BASE_SMALL to 1 and it is used to shrink a number of core data
structures. The space savings for the current batch is around 14k.
This patch:
Add CONFIG_BASE_SMALL for miscellaneous core size that don't warrant
their own options. Example users to follow.

[PATCH] lib/sort: Heapsort implementation of sort()
This patch adds a generic array sorting library routine. This is meant
to replace qsort, which has two problem areas for kernel use.
The first issue is quadratic worst-case performance. While quicksort
worst-case datasets are rarely encountered in normal scenarios, it is
in fact quite easy to construct worst cases for almost all quicksort
algorithms given source or access to an element comparison callback.
This could allow attackers to cause sorts that would otherwise take
less than a millisecond to take seconds and sorts that should take
less than a second to take weeks or months. Fixing this problem
requires randomizing pivot selection with a secure random number
generator, which is rather expensive.
The second is that quicksort's recursion tracking requires either
nontrivial amounts of stack space or dynamic memory allocation and out
of memory error handling.
By comparison, heapsort has both O(n log n) average and worst-case
performance and practically no extra storage requirements. This
version runs within 70-90% of the average performance of optimized
quicksort so it should be an acceptable replacement wherever quicksort
would be used in the kernel.
Note that this function has an extra parameter for passing in an
optimized swapping function. This is worth 10% or more over the
typical byte-by-byte exchange functions.
Benchmarks:
qsort: glibc variant 1189 bytes (+ 256/1024 stack)
qsort_3f: my simplified variant 459 bytes (+ 256/1024 stack)

The new sort routine only works if there are an even number of entries in
the ia64 exception fix-up tables. If the number of entries is odd the sort
fails, and then random get_user/put_user calls can fail.

[PATCH] random: Catastrophic reseed checks
When reseeding, we must always do a "catastrophic reseed" where we pull
enough
new bits to make the new state unguessable from outputs even if we knew the
old state. So we must do the checks against the minimum reseed amount under
the pool lock in extract_entropy.

[PATCH] Speed up /proc/pid/maps
This patch uses find_vma() to improve the read response of /proc/pid/maps.
It attempts to make the liner scan instead of quadratic walk and utilise rb
tree. Reading the file was doing sequential scan from the begining to file
position all the time, and taking a quite long time.
The improvements came from f_version/m_version and resulting in mmap_cache
match. Even if mmap_cache does not match, rb tree walk should be faster
than sequential walk. First attempt was to put the state across read
system calls into private data. Later got inspiration from wli's pid patch
using f_version in readdir of /proc. Other advantage is, f_version will be
cleared automatically by lseek.
The test program creates 32K maps and splits them into two(limited by
max_map_count sysctl) using mprotect(0). After the patch, the read time
improves from many seconds to milliseconds, and does not grow superlinearly
with number of read calls.
Help taken from Peter Swain in idea and testing.

[PATCH] posix-timers: tidy up clock interfaces and consolidate dispatch logic
This patch cleans up the posix-timers interfaces for defining clocks, and the
calls to them. It fixes some sloppy types, adds a clockid_t parameter to the
calls that lacked it, and adds a function pointer that can be used for
clock_getres. It further cleans up the posix-timers.c code using the k_clock
function pointers or default functions when no hooks are supplied,
consolidating repeated code into shared inline functions or macros. This
paves the way for adding the CPU clock hooks.
The mmtimer.c changes are untested, but obviously can't be wrong. There
aren't any other struct k_clock definitions in the tree, but any others would
need to be updated for the function signature changes.

[PATCH] posix-timers: high-resolution CPU clocks for POSIX clock_* syscalls
This patch provides support for thread and process CPU time clocks in the
POSIX clock interface. Both the existing utime and utime+stime information
(already available via getrusage et al) can be used, as well as a new
(potentially) more precise and accurate clock (which cannot distinguish user
from system time). The clock used is that provided by the `sched_clock'
function already used internally by the scheduler. This gives a way for
platforms to provide the highest-resolution CPU time tracking that is
available cheaply, and some already do so (such as x86 using TSC). Because
this clock is already sampled internally by the scheduler, this new tracking
adds only the tiniest new overhead to accomplish the bookkeeping.
Some notes:
This allows per-thread clocks to be accessed only by other threads in the
same
process. The only POSIX calls that access these are defined only for
in-process use, and having this check is necessary for the userland
implementations of the POSIX clock functions to robustly refuse stale
clockid_t's in the face of potential PID reuse.
This makes no constraint on who can see whose per-process clocks. This
information is already available for the VIRT and PROF (i.e. utime and
stime)
information via /proc. I am open to suggestions on if/how security
constraints on who can see whose clocks should be imposed.
The SCHED clock information is now available only via clock_* syscalls. This
means that per-thread information is not available outside the process.
Perhaps /proc should show sched_time as well? This would let ps et al show
this more-accurate information.
When this code is merged, it will be supported in glibc. I have written the
support and added some test programs for glibc, which are what I mainly used
to test the new kernel code. You can get those here:

[PATCH] posix-timers: fix posix-timers signals lock order
The posix-timers code establishes the locking order that k_itimer locks are
outside siglocks. However, when the signal code calls back into the
posix-timers code to reload a timer after its signal is dequeued, it holds a
siglock while calling do_schedule_next_timer, which gets a timer lock.
I'm not sure there is any deadlock scenario possible using the real-time
POSIX
timers, because of the intricate arrangement of timer firing and resetting
synchronization. But with the new CPU timers code, this deadlock pops up
right away. Dropping the siglock here certainly doesn't hurt in the
real-time
timer cases, and it really seems like the right thing here to keep the
locking
details in the interface between signals and posix-timers code
comprehensible.

[PATCH] posix-timers: CPU clock support for POSIX timers
POSIX requires that when you claim _POSIX_CPUTIME and _POSIX_THREAD_CPUTIME,
not only the clock_* calls but also timer_* calls must support the thread and
process CPU time clocks. This patch provides that support, building on my
recent additions to support these clocks in the POSIX clock_* interfaces.
This patch will not work without those changes, as well as the patch fixing
the timer lock-siglock deadlock problem.
The apparent pervasive changes to posix-timers.c are simply that some fields
of struct k_itimer have changed name and moved into a union. This was
appropriate since the data structures required for the existing real-time
timer support and for the new thread/process CPU-time timers are quite
different.
The glibc patches to support CPU time clocks using the new kernel support is
in http://people.redhat.com/roland/glibc/kernel-cpuclocks.patch, and that
includes tests for the timer support (if you build glibc with NPTL).
From: Christoph Lameter <clameter@sgi.com>
Your patch breaks the mmtimer driver because it used k_itimer values for
its own purposes. Here is a fix by defining an additional structure in
k_itimer (same approach for mmtimer as the cpu timers):

[PATCH] override RLIMIT_SIGPENDING for non-RT signals
I can read POSIX to say that the siginfo_t data must be available when
`kill' was used, as well. This patch makes it allocate the siginfo_t, even
when that exceeds {RLIMIT_SIGPENDING}, for any non-RT signal (< SIGRTMIN)
not sent by sigqueue (actually, any signal that couldn't have been faked by
a sigqueue call). Of course, in an extreme memory shortage situation, you
are SOL and violate POSIX a little before you die horribly from being out
of memory anyway.
The LEGACY_QUEUE logic already ensures that, for non-RT signals, at most
one is ever on the queue. So there really is no risk at all of unbounded
resource consumption; the usage can reach {RLIMIT_SIGPENDING} + 31, is all.
It's already the case that the limit can be exceeded by (in theory) up to
{RLIMIT_NPROC}-1 in race conditions because the bump and the limit check
are not atomic. (Obviously you can only get anywhere near that many with
assloads of preemption, but exceeding it by a few is not too unlikely.)
This patch also fixes that accounting so that it should not be possible to
exceed {RLIMIT_SIGPENDING} + SIGRTMIN-1 queue items per user in races.

[PATCH] show RLIMIT_SIGPENDING usage in /proc/PID/status
Jeremy mentioned the aggravation of not being able to tell when your
processes are using up signal queue entries and hitting the
RLIMIT_SIGPENDING limit. This patch adds a line to /proc/PID/status
showing how many queue items are in use, and allowed, for your uid.
I can certainly see the appeal of having a display of the number of queued
items specific to each process, and even the items within the process
broken down per signal number. However, those are not things that are
directly counted, and ascertaining them requires iterating through the
queue. This patch instead gives what can be readily determined in constant
time using the accounting already done. I'm not sure something more
complex is warranted just to facilitate one particular debugging need.
With this, you can see quickly that this particular problem has come up.
Then examination of each process's SigPnd/ShdPnd lines ought to give you an
indication of which processes have any queued RT signals sitting around for
a long time, and you can then attack those programs directly, though there
is no way after the fact to determine how many queued signals with the same
number a given process has (short of killing it and seeing the usage drop).
Note you may still have a mystery if the leaking programs are not leaving
pending RT signals queued, but rather preallocating queue items via
timer_create. That usage is not readily apparent in any /proc information.

[PATCH] set RLIMIT_SIGPENDING limit based on RLIMIT_NPROC
While looking into the issues Jeremy had with the RLIMIT_SIGPENDING limit,
it occurred to me that the normal setting of this limit is bizarrely low.
The initial hard limit setting (MAX_SIGPENDING) was taken from the old
max_queued_signals parameter, which was for the entire system in aggregate.
But even as a per-user limit, the 1024 value is incongruously low for this.
On my machine, RLIMIT_NPROC allows me 8192 processes, but only 1024 queued
signals, i.e. fewer even than one pending signal in each process. (To me,
this really puts in doubt the sensibility of using a per-user limit for
this rather than a per-process one, i.e. counted in sighand_struct or
signal_struct, which could have a much smaller reasonable value. I don't
recall the rationale for making this new limit per-user in the first
place.)
This patch sets the default RLIMIT_SIGPENDING limit at boot time, using the
calculation that decides the default RLIMIT_NPROC limit. This uses the
same value for those two limits, which I think is still pretty conservative
on the RLIMIT_SIGPENDING value.

[PATCH] ppc64: update irq affinity mask when migrating irqs
This patch is from Nathan Lynch <ntl@pobox.com>.
When offlining a cpu, any device interrupts which are bound to the cpu
have their affinity forcibly reset to all cpus (the default).
However, the value in /proc/irq/XXX/smp_affinity remains unchanged.
Since we're doing this while all the other cpus are stopped, it should
be safe to just call desc->handler->set_affinity and manually update
the irq_affinity array.

[PATCH] PA-RISC irq handling improvements
- Move the bits_wide parameter from txn_alloc_data to txn_alloc_irq.

In txn_alloc_irq, we can fail the allocation and continue.
- Also fix a bug where we'd only allow up to half the interrupts to be
allocated. Not a problem for iosapic machines, but might have sucked
on a really big GSC-based machine.
- Add missing irq_enter() / irq_exit()
- Allow interrupt processing to be interrupted by the timer tick so we
actually account hard interrupts. Also speed up the handling of CPU
interrupts by not masking with cpu_eiem again.
- Remove sufficiently obsolete DEBUG_IRQ code
- Remove limit on times around the loop. If we exit the loop while
interrupts are still pending, we'll only be re-interrupted as soon

Hmm, while playing around with it, I think we should create the "bus"
link on the physical device on not on the class device.
Also the current "driver" link at the class device should be removed,
cause class devices don't have a driver. Block devices never had this
misleading symlink.
From the class device we point with the "device" link to the physical
device, and only the physical device should have the "driver" and the
"bus" link, as it represents the real relationship.

[PATCH] sis900 kernel oops fix
From: Herbert Xu <herbert@gondor.apana.org.au>
Fix bug #4223.
OK, this happened because we got preempted before sis900_mii_probe
finished setting the sis_priv->mii. Theoretically this can happen
with SMP as well but I suppose the number of SMP machines with sis900
is fairly small.
Anyway, the fix is to make sure that sis900_mii_probe is done before
the device can be opened. This patch does it by moving the setup
before register_netdevice.
Since the netdev name is not available before register_netdev, I've
changed the relevant printk's to use pci_name instead. Note that
one of those printk's may be called after register_netdev as well.

Seems like it is the ioread8 in:

that fails. StickyHW is 0x83. lspci says:

In other words, it's trying to read outside of the I/O range (0x80),
which matches the fauling address.
I'm guessing my chip revision doesn't support WOL, it's a crappy noname

It does seem as if rhine_power_init checks quirks for rqWOL before

[PATCH] sysdev: remove the rwsem usage from this subsystem.
If further finer grained locking is needed, we can add a lock to the sysdev_class

lock the class drivers list. But if you do that, remember the global list also is
still
there and needs to be protected. That's why I went with a simple lock for
everything.

[NETFILTER]: Reduce call chain length in netfilter (take 2)
This is a second try to fix the long chain call lengths in netfilter.
The difference with the previous patch is that I got rid of the extra
argument. I somehow didn't see it could be done without using the 'int
*ret2' argument.
A comment on the number of arguments to nf_hook_slow: I don't think the
number of arguments should be decreased. For the bridge-nf code, f.e.,
the indev argument does not equal (*pskb)->dev (this is an answer to a
question of Rusty in the old thread).
A comment on the argument change of nf_hook_slow (sk_buff * to sk_buff
**) and the bad influence on tail call optimization possibilities. From
the discussion in the old thread it became clear that no tail call is
generated for the current code. So, I don't see why this is a reason not
to accept the patch. Furthermore, if gcc ever would become able of doing
the current code with a tail call, it should be very easy to change the
code back to the original. In the meantime, I think this patch is the
best known solution.

[PATCH] SELinux: enhanced MLS support
This patch replaces the original experimental Multi-Level Security (MLS)
implementation in SELinux with an enhanced MLS implementation contributed
by Trusted Computer Solutions (TCS).
The enhanced MLS implementation replaces the hardcoded MLS logic with a
flexible constraint-based system and replaces the compile-time option for
MLS support with a policy load-time enable based on whether MLS support was
enabled in the policy when it was built.
The latter change allows a single kernel and policy toolchain to support
both MLS and non-MLS policies. Compatibility is still provided as usual
for existing policies.

[PATCH] SELinux: pass requested protection to security_file_mmap/mprotect
hooks
This patch adds a reqprot parameter to the security_file_mmap and
security_file_mprotect hooks that is the original requested protection
value prior to any modification for read-implies-exec, and changes the
SELinux module to allow a mode of operation (controllable via a
checkreqprot setting) where it applies checks based on that protection
value rather than the protection that will be applied by the kernel,
effectively restoring SELinux's original behavior prior to the introduction
of the read-implies-exec logic in the mainline kernel. The patch also
disables execmem and execmod checking entirely on PPC32, as the PPC32 ELF
ABI presently requires RWE segments per Ulrich Drepper.
At present, the read-implies-exec logic causes SELinux to see every
mmap/mprotect read request by legacy binaries or binaries marked with
PT_GNU_STACK RWE as a read|execute request, which tends to distort policy
even if it reflects what is ultimately possible. The checkreqprot setting
allows one to set the desired behavior for SELinux, so either the current
behavior or the original behavior is possible. The checkreqprot value has
a compile-time configurable default value and can also be set via boot
parameter or at runtime via /selinux/checkreqprot if allowed by policy.
Thanks to Chris Wright, James Morris, and Colin Walters for comments on an
earlier version of the patch.

[PATCH] SELinux: fix selinux_setprocattr
This patch changes the selinux_setprocattr hook function (which handles
writes to nodes in the /proc/pid/attr directory) to ignore an optional
terminating newline at the end of the value, and to handle a value
beginning with a newline or a null in the same manner as a zero length
value (clearing the attribute for the process and resetting it to using the
default policy behavior). This change is to address the divergence from
POSIX in the existing API, as POSIX says that write(2) with a zero count
will return zero with no other effect, as well as to simplify use of the
API from scripts (although that isn't recommended).

[PATCH] ppc64: allow emulation of mfpvr on ppc64 kernel
Allow userspace programs on ppc64 to use the (privileged) mfpvr instruction
to determine the processor type. At the moment it emulates the instruction
to provide the real PVR value, though it could be made to lie in future if
for some reason we wish to restrict what CPU features userspace uses.
If nothing else this means that some existing ppc32 applications will now
run on a 64-bit kernel (the 32-bit kernel has long supported this
emulation). It will also be necessary for ppc64 perfctr support, where
userspace requires finer-grained cpu type information than the kernel in
order to correctly program the performance monitor control registers.

[PATCH] x86: memset the i386 numa pgdats in arch code
The next patch in this series will remove the arch-independent clearing of
the
pgdat's. This first patch removes the i386 dependency on that behavior.
The new i386 function, remapped_pgdat_init() takes care of initializing the
pgdats which are finally mapped after paging_init() is done. The
zone_sizes_init() call has to occur after the pgdat clearing.
zone_sizes_init() is currently called from the end of paging_init(), because
that's the first place where the pgdats could have been zeroed. However,
zone_sizes_init() really doesn't have anything to do with paging, and
probably
shouldn't be in paging_init().
Moving this call into setup_memory() allows the declaration of
zone_sizes_init() to change files as well, which means a net removal of one
#ifdef. It also provides a handy place to put the new function, far away
from
the paging code that it really has nothing to do with. Moving files required
only using highend_pfn inside of the HIGHMEM ifdef, but this saves a line of
code anyway.

[PATCH] x86: do not unnecessarily memset the pgdats
Both the pgdats and the struct zonelist are zeroed unnecessarily. The
zonelist is a member of the pgdat, so any time the pgdat is cleared, so is
the
zonelist. All of the architectures present a zeroed pgdat to the generic
code, so it's not necessary to set it again.
Not clearing it like this allows the functions to be reused by the memory
hotplug code. The only architecture which has a dependence on these clears
is
i386. The previous patch in this series fixed that up.

[PATCH] x86: disable MSI for AMD-8131
The AMD-8131 I/O APIC (device id 1022:7450/7451) does not support message
signalled interrupts. Thus, if a device driver attempts to enable msi, it
will suceed, but interrupts are not actually delivered to the cpu. The
Nforce chipsets do not seem to have this limitation. AMD confirmed that
MSI mode is unsupported with this APIC.
The following patch adds a flag to pci quirks to detect this and disable

[PATCH] uml: ptrace interface cleanup
From: Bodo Stroesser, mostly:
Gets rid of all inclusions of {sys,linux,asm}/ptrace.h since their effects
and
contents are somewhat distro- and architecture-dependent.
arch/um/sysdep/ptrace_user is now responsible for providing the system's
ptrace interfaces to UML.
As such, it is a purely userspace header, and this exposed a couple of places
where kernel files were including it. One of them needed MAX_REG_OFFSET, so
this was provided by adding a new generated header, user-constants.h, which
includes this.
Also, changed PTRACE_{PEEK,POKE}_USER to _USR since that seems to be more
standard.

[PATCH] Properly share process and session keyrings with CLONE_THREAD [try
#2]
The attached patch causes process and session keyrings to be shared
properly when CLONE_THREAD is in force. It does this by moving the keyring
pointers into struct signal_struct[*].
[*] I have a patch to rename this to struct thread_group that I'll revisit
after the advent of 2.6.11.
Furthermore, once this patch is applied, process keyrings will no longer be
allocated at fork, but will instead only be allocated when needed.
Allocating them at fork was a way of half getting around the sharing across
threads problem, but that's no longer necessary.
This revision of the patch has the documentation changes patch rolled into it

[PATCH] ext3: fix race between ext3 make block reservation and reservation window
discard
This patch fixed a race between ext3_discard_reservation() and
ext3_try_to_allocate_with_rsv().
There is a window where ext3_discard_reservation will remove an already
unlinked reservation window node from the filesystem reservation tree:
It thinks the reservation is still linked in the filesystem reservation
tree, but it is actually temperately removed from the tree by
allocate_new_reservation() when it failed to make a new reservation from
the current group and try to make a new reservation from next block
group.
Here is how it could happen:
CPU 1
try to allocate a block in group1 with given reservation window my_rsv

[PATCH] nfsd4: remove utf8 checking
RFC3530 says NFSv4 filenames are in UTF-8, and that servers "should" reject
filenames that aren't valid UTF-8. Currently we do some incomplete UTF-8
checking, but this turns out to be more of a hindrance than a help--if we
export a filesystem with non-UTF8 names, things break. We might be able to
help things if we had some idea of the exported filesystem's charset and
could
do some translation. For now, though, the simplest solution by far seems to
be just to remove the UTF-8 checks, making NFSv4's behaviour just like
NFSv2/v3's.
Similar problems exist with usernames.

[PATCH] nfsd4: remove stateowner debug counters
Get rid of these debug counters. Since they're no longer necessarily
incremented under state lock, we'd need to convert them to atomic_t to
guarantee them correct. It doesn't seem worth it.
Also, the debug checks in kmem_cache_destroy() should be sufficient for at
least one of the purposes the debugging counters existed for--we'll get a
dump_stack() if there are still stateowners left when we shut down.

[PATCH] nfsd4: move delegation decisions to lock_manager callbacks
Remove nfs4_check_deleg_recall(). Move its checks into __setlease() via two
new lock_manager callbacks, fl_mylease and fl_change, so that all leases (not
just NFSv4 lease as with nfs4_check_deleg_recall) are checked. Default
implementations of fl_mylease and fl_change are provided for the sake of the
fcntl_setlease interface. Both callbacks must always be defined.
fl_mylease:
for the NFSv4 server, this check is used to see if an existing lease
comes from the same client. For the fcntl_setlease interface, the
existing
logic is preserved. the fl_mylease check sees if the existing lease is
from the input filp.
fl_change: called if the fl_mylease returns true
the NFSv4 server does not hand out a delegation to a client that already
has one. -EAGAIN is returned. Otherwise lease_modify is used. For the
fcntl_setlease interface, the exisiting logic is preserved: The callback
used in lease_modify().

[PATCH] fat: fix writev(), add aio support
With Christoph Hellwig <hch@lst.de>
These patches adds the `-o sync' and `-o dirsync' supports to fatfs. If user
specified that option, the fatfs does traditional ordered updates by using
synchronous writes. If compared to before, these patches will show a
improvement of robustness I think.
`-o sync' - writes all buffers out before returning from syscall.
`-o dirsync' - writes the directory's metadata, and unreferencing
operations of data block.
remaining to be done
fat_generic_ioctl(), fat_notify_change(),
ATTR_ARCH of fat_xxx_write[v],
and probably, filling hole in cont_prepare_write(),
NOTE: Since fatfs doesn't have link-count, unfortunately ->rename() is
not safe order at all. It may make the shared blocks, but user
shouldn't lose the data by ->rename().
If you test this, please use the dosfstools at
http://www.zip.com.au/~akpm/linux/patches/stuff/fatfsprog...
This is fixing several bugs of dosfstools. And "2/29" patch from hpa adds
new
ioctl, the attached archive is also including the commands for testing it.
This patch fixes vectored write support on fat to do the nessecary
non-standard action done in write() aswell.
Also adds aio support and makes read/write wrappers around the aio
version.

Some rare races between ide-default and ide-disk are possible, i.e.:
* ide-default is used, I/O request is triggered (ie. /proc/ide/hd?/identify),
drive->special is cleared silently (so CHS is not initialized properly),
ide-disk is loaded and fails if drive uses CHS
* ide-disk is used, drive is resetted, ide-disk is unloaded, ide-default
takes control over drive and on the first I/O request silently clears
drive->special without restoring settings

[PATCH] new bitmap list format (for cpusets)
[This is a copy of the bitmap list format patch that I submitted to lkml
on 9 Aug 2004, after removing the prefix character fluff^Wstuff. I
include it here again just to get it associated with the current cpuset
patch, which will follow in a second email 10 seconds later. -pj]
A bitmap print and parse format that provides lists of ranges of numbers,
to be first used for by cpusets (next patch).
Cpusets provide a way to manage subsets of CPUs and Memory Nodes for
scheduling and memory placement, via a new virtual file system, usually
mounted at /dev/cpuset. Manipulation of cpusets can be done directly via
this file system, from the shell.
However, manipulating 512 bit cpumasks or 256 bit nodemasks (which will get
bigger) via hex mask strings is painful for humans.
The intention is to provide a format for the cpu and memory mask files in
/dev/cpusets that will stand the test of time. This format is supported by
a couple of new lib/bitmap.c routines, for printing and parsing these
strings. Wrappers for cpumask and nodemask are provided.

[PATCH] cpusets - big numa cpu and memory placement
This my cpuset patch, with the following changes in the last two weeks:
1) Updated to 2.6.8.1-mm1
2) [Simon Derr <Simon.Derr@bull.net>] Fix new cpuset to begin empty,
not copied from parent. Needed to avoid breaking exclusive property.
3) [Dinakar Guniguntala <dino@in.ibm.com>] Finish initializing top
cpuset from cpu_possible_map after smp_init() called.
4) [Paul Jackson <pj@sgi.com>] Check on each call to __alloc_pages()
if the current tasks cpuset mems_allowed has changed. Use a cpuset
generation number, bumped on any cpuset memory placement change,
to make this check efficient. Update the tasks mems_allowed from
its cpuset, if the cpuset has changed.
5) [Paul Jackson <pj@sgi.com>] If a task is moved to another cpuset,
then update its cpus_allowed, using set_cpus_allowed().
6) [Paul Jackson <pj@sgi.com>] Update Documentation/cpusets.txt to
reflect above changes (4) and (5).
I continue to recommend the following patch for inclusion in your 2.6.9-*mm
series, when that opens. It provides an important facility for high
performance computing on large systems. Simon Derr of Bull (France) and
myself are the primary authors. Erich Focht has indicated that NEC is also
a potential user of this patch on the TX-7 NUMA machines, and that he
"would very much welcome the inclusion of cpusets."
I offer this update to lkml, in order to invite continued feedback.
The one prerequiste patch for this cpuset patch was just posted before this
one. That was a patch to provide a new bitmap list format, of which
cpusets is the first user.
This patch has been built on top of 2.6.8.1-mm1, for the arch's:
i386 x86_64 sparc ia64 powerpc-405 powerpc-750 sparc64
with and without CONFIG_CPUSET. It has been booted and tested on ia64
(sn2_defconfig, SN2 hardware). The 'alpha' arch also built, except for
what seems to be an unrelated toolchain problem (crosstool ld sigsegv) in
the final link step.
===
Cpusets provide a mechanism for assigning a set of CPUs and Memory Nodes to
a set of tasks.
Cpusets constrain the CPU and Memory placement of tasks to only the
processor and memory resources within a tasks current cpuset. They form a
nested hierarchy visible in a virtual file system. These are the essential
hooks, beyond what is already present, required to manage dynamic job
placement on large systems.
Cpusets require small kernel hooks in init, exit, fork, mempolicy,
sched_setaffinity, page_alloc and vmscan. And they require a "struct
cpuset" pointer, a cpuset_mems_generation, and a "mems_allowed" nodemask_t
(to go along with the "cpus_allowed" cpumask_t that's already there) in
each task struct.
These hooks:
1) establish and propagate cpusets,
2) enforce CPU placement in sched_setaffinity,
3) enforce Memory placement in mbind and sys_set_mempolicy,
4) restrict page allocation and scanning to mems_allowed, and
5) restrict migration and set_cpus_allowed to cpus_allowed.
The other required hook, restricting task scheduling to CPUs in a tasks
cpus_allowed mask, is already present.
Cpusets extend the usefulness of, the existing placement support that was
added to Linux 2.6 kernels: sched_setaffinity() for CPU placement, and
mbind() and set_mempolicy() for memory placement. On smaller or dedicated
use systems, the existing calls are often sufficient.
On larger NUMA systems, running more than one, performance critical, job,
it is necessary to be able to manage jobs in their entirety. This includes
providing a job with exclusive CPU and memory that no other job can use,
and being able to list all tasks currently in a cpuset.
A given job running within a cpuset, would likely use the existing
placement calls to manage its CPU and memory placement in more detail.
Cpusets are named, nested sets of CPUs and Memory Nodes. Each cpuset is
represented by a directory in the cpuset virtual file system, normally
mounted at /dev/cpuset.
Each cpuset directory provides the following files, which can be
read and written:
cpus:
List of CPUs allowed to tasks in that cpuset.
mems:
List of Memory Nodes allowed to tasks in that cpuset.
tasks:
List of pid's of tasks in that cpuset.
cpu_exclusive:
Flag (0 or 1) - if set, cpuset has exclusive use of
its CPUs (no sibling or cousin cpuset may overlap CPUs).
mem_exclusive:
Flag (0 or 1) - if set, cpuset has exclusive use of
its Memory Nodes (no sibling or cousin may overlap).
notify_on_release:
Flag (0 or 1) - if set, then /sbin/cpuset_release_agent
will be invoked, with the name (/dev/cpuset relative path)
of that cpuset in argv[1], when the last user of it (task
or child cpuset) goes away. This supports automatic
cleanup of abandoned cpusets.
In addition one new filetype is added to the /proc file system:
/proc/<pid>/cpuset:
For each task (pid), list its cpuset path, relative to the
root of the cpuset file system. This file is read-only.
New cpusets are created using 'mkdir' (at the shell or in C). Old ones are
removed using 'rmdir'. The above files are accessed using read(2) and
write(2) system calls, or shell commands such as 'cat' and 'echo'.
The CPUs and Memory Nodes in a given cpuset are always a subset of its
parent. The root cpuset has all possible CPUs and Memory Nodes in the
system. A cpuset may be exclusive (cpu or memory) only if its parent is
similarly exclusive.
See further Documentation/cpusets.txt, at the top of the following
patch.
/proc interface:
It is useful, when learning and making new uses of cpusets and placement to
be
able to see what are the current value of a tasks cpus_allowed and
mems_allowed, which are the actual placement used by the kernel scheduler and
memory allocator.
The cpus_allowed and mems_allowed values are needed by user space apps that
are micromanaging placement, such as when moving an app to a obtained by
that app within its cpuset using sched_setaffinity, mbind and
set_mempolicy.
The cpus_allowed value is also available via the sched_getaffinity system
call. But since the entire rest of the cpuset API, including the display
of mems_allowed added here, is via an ascii style presentation in /proc and
/dev/cpuset, it is worth the extra couple lines of code to display
cpus_allowed in the same way.
This patch adds the display of these two fields to the 'status' file in the
/proc/<pid> directory of each task. The fields are only added if
CONFIG_CPUSETS is enabled (which is also needed to define the mems_allowed
field of each task). The new output lines look like:
$ tail -2 /proc/1/status
Cpus_allowed: ffffffff,ffffffff,ffffffff,ffffffff
Mems_allowed: ffffffff,ffffffff

I've also a question here: skeletonfb says that xxxfb_setcolreg() should
return a negative errno on error. However, if the register number being
accessed is out of bounds, 1 is returned. Shouldn't it be better to return
-EINVAL instead? By looking at fbcmap.c, the retval isn't being checked

* Only Geode GX1 (with CS5530 companion chip) is supported.
* Tested resolutions: 640x480 to 1280x1024.
* Supported bit depths: 8 bit palette, 16 bit RGB 5-6-5.
* CRT output only.
* No accelerated features.
* Compression is not enabled.
* flat panel support (panel=<x>x<y> option). (Only one 640x480
panel
has been tested though.)
* blank function for display blanking/powersaving.
* crt=<n> option to enable/disable the CRT output.

[PATCH] nvidiafb: Add update framebuffer driver for nVidia chipsets
Because nVidia keeps pumping out new graphics chipsets, it is becoming
harder to add support for these with the old rivafb code. Currently, rivafb
can properly support NV_ARCH_20 chipsets and older.
Instead of rewriting rivafb to support the latest chipsets, I've decided to
write a new driver, called nvidiafb. The aim is to closely follow Xorg
development.
Currently, this driver is based on the most recent CVS Xorg nv driver. Main
- console acceleration for all chipsets
- uses DMA instead of PIO
- better LCD/digital output support
- better monitor detection
- support for Riva128 will be dropped as it cannot do DMA, rivafb
will remain as the driver for this chipset
It should work with Xorg/XFree86 nv driver, but as with rivafb, is not
compatible with the proprietary nvidia driver.
Once the code becomes stable, rivafb code will be trimmed to only support the
Riva128 and perhaps some of the older chipsets. The code has been tested on
several nVidia graphics card on x86 and x86_64. I'm still waiting for
feedback from Guido Guenther regarding ppc.
This need not go to mainline immediately, as I would prefer the code to
receive rigorous testing in the mm tree.

[PATCH] ppc32: uninorth-agp suspend support
This patch adds suspend/resume support to the Apple UniNorth AGP bridge to
make sure AGP is properly disabled when the machine goes to sleep. Without
this, the r300 based laptops will fail to wakeup from sleep when using the
new experimental r300 DRI driver. It should also improve reliablility in
general with other chips.
Unfortunately, uninorth-agp is just a "sibling" of the video chip on the
PCI bus, and thus ends up beeing called either before the video chip
suspend routine, or after, depending on the HW layout or other random
things.
To make sure the device side of AGP is always disabled first and that we
never touch the device after having put it into D2 state (which can be
deadly), I also need the separate patch to radeonfb and aty128fb which will
make them disabled their own side if not already done by the bridge driver.

[PATCH] fbdev: Add mode changing via sysfs
This is a first pass at adding two new sysfs attributes to
/sys/class/graphics/fb0 for setting modes. There are two attributes: modes
which contains a list of valid modes, and mode which is the current mode. To
switch modes echo one of the entries from the modes list to the mode
attribute.
The D,V,S on the modes represents Detailed, Vesa, Standard from the DDC info.
modes is root writable. It can also be used to set the list of modes. For
example a /etc file could add modes that are not in the monitor's DDC.
mode is user writable. PAM would set ownership of mode at user login time.
This provides a safe way for a user to set the mode without being root. You
can only set the mode to one of the modes on the list.

[PATCH] device-mapper: multipath
The core device-mapper multipath and path-selector code.
Paths are grouped into an ordered list of Priority Groups. Each Priority
Group has a Path Selector which chooses which of the Priority Group's paths
is
to be used for each bio e.g. according to some load-balancing algorithm. If
a bio generates an error, the path that it used gets disabled and an
alternative path is tried. If all the paths in a Priority Group fail,
another
Priority Group is selected.
There are management commands fail_path and reinstate_path. A path tester
(currently implemented in userspace) is responsible for monitoring paths that
have failed and reinstating them should they come back.
Other management commands can be use to switch immediately to a specified

tried after there are no more left.
As a last resort there is an option to 'queue_if_no_path' which queues I/O if
all paths have failed e.g. temporarily during a firmware update or if the
userspace daemon is slow reinstating paths.
The userspace multipath tools are available at:

[PATCH] device-mapper: multipath round-robin path selector.
A very basic path selector: round-robin.
It uses in turn each path that has not been disabled.
By default, it instructs core multipath to use each path it supplies for 1000
bios, but a different repeat_count can be set against any path to provide
primitive load-balancing across unequal paths.

[PATCH] device-mapper: multipath hardware handler
Each multipath instance can use a Hardware Handler with hooks for the
particular hardware you're using.
This patch provides the hw_handler infrastructure.
So far 3 hooks are available:
A status function invoked by device-mapper table and status requests.
An initialisation function called when a Priority Group is selected for
use but before any I/O is sent to it. This function should return straight
away, and I/O is queued until dm_pg_init_complete() is called indicating
whether or not the initialisation was successful. The are three error
flags, any or all of which may be set: MP_FAIL_PATH, MP_BYPASS_PG,
MP_ERROR_IO.
An error handler which gets the opportunity to decode any error that a bio
generated. Patches are pending to make scsi error details available for
dm_scsi_err_handler() to decode.

VFS: Retry pathname resolution after encountering ESTALE
Add a mechanism for the VFS layer to retry pathname resolution if a file
system returns ESTALE at any point during the resolution process. Pathname
resolution is retried once from the first component, using all real lookup
requests.
This provides effective recovery for most cases where files or directories
have been replaced by other remote file system clients. It also provides
a foundation to build a mechanism by which file system clients can fail
over transparently to a replicated server.
Test-plan:
Combinations of rsync and "ls -l" on multiple clients. No stale file
handles
should be after directory trees are replaced. Standard performance tests;
little or no loss of performance is expected.

Revert AGP card->bridge mapping checks.
They don't work, as per Ben Herrenschmidt:
"device->bus may be a host bridge, which has no bus->self -> Ooops.
Unfortunately, there is no sane way to match a host bridge with it's
eventual "self" device if it has any. The only way would be to scan for
devices of class host bridge, but that isn't even 100% reliable.
The result is that the self device (AGP bridge device) is generally a
sibling of the actual AGP card, which is source of interesting problems,
especially with power management."

Fix up AGP device discovery.
The previous revert needed some more work to make it actually work.
<paulus@samba.org>
[PATCH] AGP 3.0 bogosities
There are other bogosities in drivers/char/agp/generic.c. I can't
believe Dave ever tested that code with an AGP 3.0 device. If you pass
in a mode that has the AGP 3.0 bit set, agp_v3_parse_one() will first
clear that bit (and print a message), and then complain because you
haven't got that bit set in the mode, with a message that the caller is
broken. Furthermore, if the mode passed in has both the 4x and 8x bits
set, the new code will give you 4x where the old code would give you 8x
(which is what the caller wanted).
The patch below fixes this. It will work in the 99.99% of cases where
we have one AGP bridge and one AGP video card. We should eventually
cope with multiple AGP bridges, but doing the matching of bridges to
video cards is a hard problem because the video card is not necessarily
a child or sibling of the PCI device that we use for controlling the AGP
bridge. I think we need to see an actual example of a system with
multiple AGP bridges first.
Oh, and by the way, I have 3D working relatively well on my G5 with a
64-bit kernel (and 32-bit X server and clients), which is why I care
about AGP 3.0 support. :)

[SUNGEM]: Rework PM handling and fix MAC reset on stuck receiver.
This patch updates the sungem driver. I reworked all of the PM stuff, making
it
less prone to races, probably simpler to read as well, and I no longer shut
the
PHY down when the interface is down so that things like laptop-net no longer
die (the gain in power consumption was minimal, not worth the pain). I also
implemented basic WOL support.
There is still something I'm not totally happy with in the locking
(explained in the comment at the beginning), basically too much locking and a
couple of places with delays in locks. I will try to improve these later on.
It also adds a fix for a MAC reset issue when the receiver gets stuck.

[PATCH] ppc64: Add basic support for the SMU chip in iMac G5
The iMac G5 and latest single-cpu PowerMac G5 have seen the venerable PMU
(Power Management Unit) chip been sent to well deserved retirement. It has
been replaced by a newcomer, the SMU (System Management Unit ?) which is of
course totally undocumented and has no open source darwin driver... The
SMU chip is responsible of initializing the chipset & CPU (boot process),
power supply control, real time clock, fan control, provides some i2c
busses, etc... etc... etc...
This is a very basic driver based on the Open Firmware methods for
accessing this chip. It provides synchronous functions only, and does
restart, shutdown, and real time clock access. There is still no fan
control, at least not until we have figured out how to access the fans via
the SMU.
The initial code was written by J. Mayer <l_indien@magic.fr>, I mostly
rewrote it to better adhere to our coding style standards ;)
The patch also updates the g5_defconfig to include the SMU support by
default.

3) Add zoom_video handler support.
TI12XX handlers can disable CLKRUN feature with "disable_clkrun" option.
Some
devices or bridge itself seems to be needing this option as workaround.

[PATCH] pcmcia: mark resource setup as done
PCMCIA device registration should only happen if we're quite confident
there are resources available to at least map the CIS space -- else we can't
determine manfid/cardid, whether it is a multifunction card, etc. So,
add a flag to struct pcmcia_socket which denotes that -- and also whether
resources were added the "old" adjust_resource_info way. On static sockets,
it is activated upon registration, on non-static sockets, it is set upon an
echo'ing of anything into

[PATCH] re-inline sched functions
This could be part of the unknown 2% performance regression with
db transaction processing benchmark.
The four functions in the following patch use to be inline. They
are un-inlined since 2.6.7.
We measured that by re-inline them back on 2.6.9, it improves performance
for db transaction processing benchmark, +0.2% (on real hardware :-)
The cost is certainly larger kernel size, cost 928 bytes on x86, and
2728 bytes on ia64. But certainly worth the money for enterprise
customer since they improve performance on enterprise workload.

[PATCH] PA-RISC GSC interrupt fixes
Two problems occurred with the recent switch to virtual interrupt numbers.
The first is that two devices (eg Lasi PS/2 mouse and keyboard) can
share the same physical interrupt and should therefore share the same
virtual interrupt rather than have a new one assigned to them. Fix this
by initialising the global_irq array to NO_IRQ, then checking the array
before assigning a new one.
The second is that some GSC devices (eg HIL and EISA) can have
two interrupts; one for normal interrupts and the other for NMI or
high-priority. To fix this, I introduced an auxiliary IRQ to the
parisc_device and fill it in in Asp and Wax.

[PATCH] Fix i2c messsage flags in video drivers
While working on the saa7110 driver I found a problem with the way
various video drivers (found on Zoran-based boards) prepare i2c messages
to be used by i2c_transfer. The drivers improperly copy the i2c client
flags as the message flags, while both sets are mostly unrelated. The
net effect in this case is to trigger an I2C block read instead of the
expected I2C block write. The fix is simply not to pass any flag,
because none are needed.
I think this patch qualifies hands down as a "critical bug fix" to be
included in whatever bug-fix-only trees exist these days. As far as I
can see, all Zoran-based boards are broken in 2.6.11 without this patch.

[PATCH] sis900 kernel oops fix
Backport of fix described below.
From: Herbert Xu <herbert@gondor.apana.org.au>
Fix bug #4223.
OK, this happened because we got preempted before sis900_mii_probe
finished setting the sis_priv->mii. Theoretically this can happen
with SMP as well but I suppose the number of SMP machines with sis900
is fairly small.
Anyway, the fix is to make sure that sis900_mii_probe is done before
the device can be opened. This patch does it by moving the setup
before register_netdevice.
Since the netdev name is not available before register_netdev, I've
changed the relevant printk's to use pci_name instead. Note that
one of those printk's may be called after register_netdev as well.

In other words, it's trying to read outside of the I/O range (0x80),
which matches the fauling address.
I'm guessing my chip revision doesn't support WOL, it's a crappy noname

It does seem as if rhine_power_init checks quirks for rqWOL before

[PATCH] x86: further EFLAGS and ptrace cleanups/fixes
This patch further cleans up the appearance of TF in eflags when ptrace is
involved. With this, PTRACE_SINGLESTEP will not cause TF to appear in
eflags as seen by PTRACE_GETREGS and the like, when the instruction faulted
for some reason other than the single-step trap.
This moves the check added by Dan's patch from setup_sigcontext to
handle_signal. This is a cosmetic difference, but I think it makes more
sense to consolidate all the "reset registers to canonical state" work in
the same place (i.e. put it with the syscall rollback code), separate from
the signal handler setup.
The change that matters is moving the similar check out of do_debug,
where it only covers the case of a single-step trap. Instead, it goes
into the ptrace_signal_deliver macro, which is called before the ptrace
stop for whatever signal results from whatever kind of fault in that
instruction (or asynchronous signal). With that, the handle_signal
check is still needed only for the case of PTRACE_SINGLESTEP with a
handled signal.

[PATCH] sym2 version 2.2.0
Docs
- The sym53c8xx= kernel parameter no longer exists
- Correct a typo
Bugfixes
- The driver really isn't capable of dealing with 64-bit bus addresses
yet, so bail out early
- Get rid of SYM_SCAN_TARGETS_HILO (which had no effect) and set the
shost->reverse_ordering flag instead
- Associate a scsi_device with the target in slave_alloc instead of
slave_configure
Printk cleanups
- Use dev_warn/dev_info where possible
- Delete PRINT_ADDR, PRINT_TARGET and PRINT_LUN
- Remove sym_print_target() and sym_print_lun()
- Make sym_print_addr() call dev_info
Memory allocation related
- Delete non-dma allocators; use kmalloc/kcalloc directly instead
- Move memory allocation wrappers from sym_glue to sym_malloc
- Get rid of m_addr_t; use void * or dma_addr_t as appropriate
- Change m_pool_ident_t from a struct pci_dev * to a struct device *
- Use dma_alloc_coherent() instead of pci_alloc_consistent()
Negotiation related
- Move scsi_transport_spi.h include from sym_glue.c to sym_glue.h
- Store the current transfer contract settings in the starget attributes
- Delete sym2_get_offset(), sym2_get_period(), sym2_get_width(),
sym2_get_dt(), sym2_get_iu() and sym2_get_qas()
- Use spi_support_wide() (and friends) instead of scsi_device_wide()
- We don't need tinfo.prev -- we can tell if the contract changed
- Delete SYM_OPT_ANNOUNCE_TRANSFER_RATE
- Use spi_display_xfer_agreement()
- Use sdev->scsi_level instead of the never-set tinfo.curr.scsi_version
- Instead of checking current xfer settings against our goal, use a
check_nego flag.
- Get rid of sym_tinfo and use sym_trans directly.
- Split the sym_trans options into flags
- Change width from an u8 into a flag
- Delete sym_misc.c
- Remove sym_xpt_async_nego_wide
Linuxisation
- Use udelay() directly instead of indirecting through UDELAY and sym_udelay
- Rename some scsi_cmnd pointers from ccb or csio to cmd
- Use simple_strtoul() instead of a handwritten parser
- SKIP_SPACES was always being used with 1 as a parameter, and was
implicitly
modifying ptr and len.
- GET_INT_ARG was doing the same with ptr and len.
- Use pci_iomap(), pci_iounmap(), ioread8() et al
- Delete the sym_data_dmamap_*() macros
- Replace SYM_CONF_IOMAPPED with CONFIG_SCSI_SYM53C8XX_IOMAPPED
- Delete unused SYM_HAVE_SCCB, SYM_HAVE_M_SVTOB, SYM_HAVE_M_SPOOL
Misc cleanup
- Move sym_conf.h into sym53c8xx.h
- Eliminate the unused SYM_SETUP_MAX_LUN, SYM_SCMD_PTR
- SYM_SETUP_PCI_PARITY and SYM_SETUP_SCSI_PARITY are always defined;
simplify
- Rename sym_pci_chip to sym_chip
- Write sym_get_hcb() to hide nasty macro abuse
- sym_lp() doesn't need to take the sym_hcb as an argument
- sym_get_ccb() works better if you give it the cmd instead of the id/lun
- We don't use cmd->host_scribble, host->dma_channel, host->n_io_port,
host->io_port, host->base or host->irq; stop initialising them.
- sym_tune_dev_queuing() works better if you give it the tcb rather than
the hcb and target
- Get rid of sym_driver_name(), just use SYM_DRIVER_NAME directly
- OUTB/INB/etc macros implicitly use the hcb pointer; pass it explictly
instead
- Map the BARs early instead of mapping and unmapping them as necessary
- Automatically fall back to ioport accesses if iomem isn't available
- Get rid of tcb_p, lcb_p and ccb_p typedefs
- Delete support for big endian chips -- 8xx chips can't be in BE mode
- Inline sym_slot into sym_device
- Inline sym_printb_hex() into sym_printl_hex()
- Don't cast function return values to void
- Introduce sym_nvram_type()
- Pass the hcb and starget to sym_check_goals since we already have them
in the caller
- Some 0/NULL cleanup
- Embed the sense buffer in the CCB so it doesn't need to be allocated
separately

There is a bug booting with CONFIG_NUMA=y, CONFIG_X86_GENERICARCH=y, and
booting on a non-NUMA system. While not the most common configuration, it
should surely be supported.
memmap_init_zone() is the first user to do pfn_to_nid(), which relies on
physnode_map[] to be done properly. memory_present() was supposed to do
that, but never got called for the flat configuration, so pfn_to_nid() was

[PATCH] orphaned pagecache memleak fix
Chris found that with data journaling a reiserfs pagecache may be truncate
while still pinned. The truncation removes the page->mapping, but the page
is still listed in the VM queues because it still has buffers. Then during
the journaling process, a buffer is marked dirty and that sets the PG_dirty
bitflag as well (in mark_buffer_dirty). After that the page is leaked
because it's both dirty and without a mapping.
So we must allow pages without mapping and dirty to reach the PagePrivate
check. The page->mapping will be checked again right after the PagePrivate
check.

[PATCH] ptwalk: change_protection
Begin the pagetable walker cleanup with a straightforward example,
mprotect's change_protection. Started out from Nick Piggin's for_each
proposal, but I prefer less hidden; and these are all do while loops,
which degrade slightly when converted to for loops.
Firmly agree with Andi and Nick that addr,end is the way to go: size is
good at the user interface level, but unhelpful down in the loops. And
the habit of an "address" which is actually an offset from some base has
bitten us several times: use proper address at each level, whyever not?
Don't apply each mask at two levels: all we need is a set of macros
pgd_addr_end, pud_addr_end, pmd_addr_end to give the address of the end
of each range. Which need to take the min of two addresses, with 0 as
the greatest. Started out with a different macro, assumed end never 0;
but clear_page_range (alone) might be passed end 0 by some out-of-tree
memory layouts: could special case it, but this macro compiles smaller.
Check "addr != end" instead of "addr < end" to work on that end 0 case.

[PATCH] ptwalk: copy_pte_range hang
This patch is the odd-one-out of the sequence. The one before adjusted
copy_pte_range from a for loop to a do while loop, and it was therefore
simplest to check for lockbreak before copying pte: possibility that it
might keep getting preempted without making progress under some loads.
Some loads such as startup: 2*HT*P4 with preemption cannot even reach
multiuser login. Suspect needs_lockbreak is broken, can get in a state
when it remains forever true. Investigate that later: for now, and for
all time, it makes sense to aim for a little progress before breaking
out; and we can manage more pte_nones than copies.

[PATCH] no arch-specific mem_map init
So, this patch started out with me trying to keep from passing contiguous,
node-specific mem_map into free_area_init_node() and cousins. Instead, I
relied on some calls to pfn_to_page().
This works fine and dandy when all you need is the pgdat->node_mem_map to
do pfn_to_page(). However, the non-NUMA/DISCONTIG architectures use the
real, global mem_map[] instead of a node_mem_map in the pfn_to_page()
calculation. So, I ended up effectively trying to initialize mem_map from
itself, when it was NULL. That was bad, and caused some very pretty colors
on someone's screen when he tested it.
So, I had to make sure to initialize the global mem_map[] before calling
into free_area_init_node(). Then, I realized how many architectures do
this on their own, and have comments like this:
/* XXX: MRB-remove - this doesn't seem sane, should this be done somewhere else
?*/
mem_map = NODE_DATA(0)->node_mem_map;
The following patch does what my first one did (don't pass mem_map into the
init functions), incorporates Jesse Barnes' ia64 fixes on top of that, and
gets rid of all but one of the global mem_map initializations (parisc is
weird). It also magically removes more code than it adds. It could be
smaller, but I shamelessly added some comments.
Boot-tested on ppc64, i386 (NUMAQ, plain SMP, laptop), UML (i386).

[PATCH] Unbacked shared memory not included in ELF core dump
We're currently not including sysv shared memory segments in coredumps.
This patch intends to include any shared mapping whose target file has zero
links. That covers sysv shm and MAP_ANON|MAP_SHARED mmap's (which I think
are only ever useful if you want to share pages with a fork'd child). I
think it also covers a regular file that was unlinked but is still mmap'd.
It doesn't cover mapping of a tmpfs file like /dev/shm/foo, but those are
still available to be seen after your program crashes, until reboot.
Note that this still omits plenty of cases that the old code would include,
such as all writable shared mappings of regular files. It also will

Some Book-E implementations (e500) do not implement the userland load/store

[PATCH] swsusp: use non-contiguous memory on resume
The following patch is designed to fix a problem in the current
implementation
of swsusp in mainline kernels. Namely, swsusp uses an array of page backup
entries (aka pagedir) to store pointers to memory pages that must be saved
during suspend and restored during resume.
Unfortunately, the pagedir has to be located in a contiguous chunk of memory
and it sometimes turns out that an 8-order or even 9-order allocation is
needed for this purpose. It sometimes is impossible to get such an
allocation
and swsusp may fail during either suspend or resume due to the lack of
memory,
although theoretically there is enough free memory for it to succeed.
Moreover, swsusp is more likely to fail for this reason during resume, which
means that it may fail during resume after a successful suspend (this
actually
has happened for some people, including me :-)) and this, potentially, may
lead to the loss of data.
The problem is fixed by replacing the pagedir with a linklist so that
high-order memory allocations are avoided (the patches make swsusp use only
0-order allocations). Unfortunately this means that it's necessary to change
assembly routines used to restore the image after it's been loaded from swap
so that they walk the list instead of walking the array.
This patch makes swsusp allocate only individual pages during resume. it
contains the necessary changes to the assembly routines etc. for i386 and
x86-64.

[PATCH] swsusp: enable resume from initrd
From: <mjg59@scrf.ucam.org>
When using a fully modularized kernel it is necessary to activate resume
manually as the device node might not be available during kernel init.
This patch implements a new sysfs attribute '/sys/power/resume' which allows
for manual activation of software resume. When read from it prints the
configured resume device in 'major:minor' format. When written to it expects
a device in 'major:minor' format. This device is then checked for a
suspended
image and resume is started if a valid image is found. The original
functionality is left in place.
It should be used from initramfs, or with care.

A few tiny cleanups for arch/sparc/kernel/ptrace.c::do_ptrace post the big

'ret' shadows a variable of the same name in the enclosing scope, rename it.
The assignment of -EFAULT to 'i' exactely mirrors what the old verify_area
code did, but that was only to use 'i' to check the return value of
verify_area. Now that we check access_ok directly and 'i' is initialized in
the for loop a few lines below anyway, the asignment of -EFAULT to i is
bogus,
just pass pass EFAULT directly as the second arg to pt_error_return.
Also a few tiny whitespace cleanups - 'if ()' vs 'if()'.

[PATCH] Make loglevels in init/main.c a little more sane.
This patch modifies a few of the printk() loglevels used in init/main.c in
an attempt to make them a bit more appropriate.
The default loglevel is KERN_WARNING, but a few printk's without explicit
loglevel are not (in my oppinion) warnings, so add proper warning levels -
for instance; telling the user how many CPU's were brought up is hardly a
warning, make it KERN_INFO instead. The initial printing of linux_banner
is not a warning condition, I'd say it's more of a NOTICE or even INFO
condition - I've made it KERN_NOTICE just as the printing of the kernel
command line. A few printk's without explicit loglevel do match the
default one, but I've made them explicit (the default could change in the
future, and if it does then explicitly setting the proper loglevel is a
nice thing).

[PATCH] mark BLK_DEV_PS2 as BROKEN
Andries Brouwer proposed this patch with the following comment:
As observed earlier, ps2esdi was broken as a module, and the passing of
geometry boot parameters is broken. But does it still work with kernels
2.3 or later? I think it does, but failed to verify that.
I found an IBM PS/2 model 70-A21 with 8 MB and 120 MB ESDI disk.
Tried a few distribution boot floppies to see whether they would boot.
Slackware has special ibmmca bootdisks.
SW 3.3 - Linux 2.1.43 - boots fine
SW 4.0 - Linux 2.2.6 - hangs
SW 7.0 - Linux 2.2.13 - boots fine
SW 8.1 - Linux 2.4.18 - boots, but every single command is killed by OOM
SW 10.0 - Linux 2.4.26 - kernel panic: no 386 supported
Then Debian:
Woody - Linux 2.2.10 - boots fine, but the rootdisk hangs
Sarge - Linux 2.4.27 - does not recognize the ESDI disk, and the rootdisk
crashes by OOM.
So, good luck with 2.1 and 2.2 kernels, only failures with later kernels.
What about other people? The two major Linux/MCA sites were
http://glycerine.itsmm.uni.edu/mca (also referenced in Documentation/mca.txt)
but it doesnt exist any longer, and http://www.dgmicro.com/mca/,
which still exists ("last update: Jan 28 1999"), but the binaries
it refers to live on ftp.dgmicro.com, which isn't there anymore.
Concerning the speed:
I measured this ESDI disk under Linux as transferring 50 kB/s,
that is 4% of the speed the IBM specs claim. Also other Linux users
complained that the disk is much faster under DOS.
My proposal for this patch would be to get it into one 2.6 kernel (is it
too late for 2.6.11?) and wait if anyone was still using it and screams,
and remove it a few months later otherwise.

expected. The current code uses TASK_INTERRUPTIBLE, but does not care
about signals, so I believe msleep() should be ok.

[PATCH] ftape/fdc-io: insert set_current_state() before schedule_timeout()
Inserts a set_current_state(TASK_INTERRUPTIBLE) before the schedule_timeout()
call. Without this change, after the first iteration of the loop,
schedule_timeout() will not only return immediately, but the loop will break,
as the conditional will no longer be satisfied. In fact, this conditional
makes little sense given the workings of schedule_timeout. The timeout
variable is ignored, as well, and I'm fairly certain that it should be
included in the loop conditional. That way, if the timeout expires before a
signal hits, -ETIME will be returned by fdc_interrupt_wait() instead of
-EINTR.

[PATCH] ipr: Device remove cleanup
If a device disappears across an adapter reset, ipr schedules the device to
be

end up getting sent to the adapter using a now invalid adapter resource
handle.
Usually, the adapter will just fail the command and the failure will end up
looking like a selection timeout, but it is possible the resource handle
has been re-used by the adapter and we could be sending an op to a different
device than we think we are. This patch closes this window.

[NETLINK]: Fix multicast bind/autobind race
netlink_autobind has always set nlk_sk(sk)->groups to zero. This is
unnecessary because sk_alloc already zeroes the entire structure.
Since a socket can only be bound once netlink_autobind doesn't need
to zero groups at all.
This had been safe until I added mc_list. Now it is possible for
netlink_bind to race against netlink_autobind running on the same
socket on another CPU. The result would be a socket that's on
mc_list with groups set to zero. This socket will be left on the
list even after it is destroyed.
The fix is to remove the zeroing in netlink_autobind.

[PATCH] SCSI tape security: require CAP_ADMIN for SG_IO etc.
The kernel currently allows any user permitted to access the tape device file
to send the tape drive commands that may either make the tape drivers
internal
state inconsistent or to change the drive parameters so that other users find
the drive to be unusable. This patch changes ioctl handling so that SG_IO,
SCSI_IOCTL_COMMAND, etc. require CAP_ADMIN. This solves the consistency
problems for SCSI tapes. The st driver provides user-accessible commands to
change the drive parameters that users may need to access.
The SCSI command permissions were discussed widely on the linux lists but
this
did not result in any useful refinement of the permissions. It may very well
be that the tape drives are the only devices that users are sometimes given
permissions to access and that have security problems with the current
command
filtering. This patch solves the problem for tapes and no more elaborate
patches are needed.

Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
<jejb@mulgrave.(none)>
From: James.Smart@Emulex.Com
FC Remote Port Patch
This is the reworked patch for fc_remote ports.
It started with the "patch2" converted for scsi-misc-2.6 (and
updated for the revised midlayer scsi target implementation)
Incorporates Andrew Vasquez's updates
Adds scsi target scanning on behalf of the driver based on
addition of a per-host workq.
This patch adds support for FC Remote Ports (which may or may not
be FCP targets) to the fc transport. The attributes for the ports are
in support of HBAAPI. This patch also implements consistent scsi target
id bindings for the remote ports.
This patch also moves the dev_loss attribute from the target-level
fc_transport device to the remote port device. It also deletes the
link_down attribute. The fc_target_block and fc_target_unblock
routines have been replaced by fc_remote_port_block and
fc_remote_port_unblock. The fc_host_block/unblock functions have
been removed (unused).
A new interface has been created - fc_remove_host(), which a driver
must call immediately prior to scsi_remove_host() when unloading.
This tears down the transport, starget, and sdev devices.
The transport, which utilizes the midlayer mods to insert transport
entities between the shost and starget, results in a device tree
such as the following:
/sys/class/fc_host/host4/device/rport-4:0-0/target4:0:0/4:0:0:0

[IPSEC]: Revert ip{,6}_append_data() dst_mtu() conversion.
This patch is wrong. This is the *one* place where we do need to
use the path MTU. The reason is that when the packet is fragmented
we only pay for the IPsec overhead once over all and not once for
each fragment.
Please revert it for now.
The trailer_len in ip_append_data is not quite right as the trailer's
length depends on the length of the entire packet. However, it should
be harmless since ESP knows how to extend the packet when necessary.

As it is ipt_REJECT doesn't work at all with IPsec. Despite my efforts

ipt_REJECT also had a number of deviations from icmp_send which seems to

umount: avoid racy block-size set
Setting the block size back to the original blocksize at umount time

Just getting bdev_lock instead causes other issues, namely AB-BA deadlocks
with /proc/meminfo etc. Just drop it, and replace with a "sync_blockdev()"
to cause a flush (which was a side effect of changing the blocksize before).

[PATCH] PPC64 Implement non-executable stacks
This patch, by Jake Moilanen with some further hacking from me, adds a
real execute permission bit to the linux PTEs on PPC64, and connects
that into the kernel infrastructure for implementing non-executable
stacks and heaps. This means that on any PPC64 cpu since the POWER4
(i.e. POWER4, PPC970, PPC970FX, POWER4+, POWER5) you will get a
segfault if you try to execute instructions from a region that doesn't
have PROT_EXEC permission. The patch also marks the pages of the
linear mapping that aren't part of the kernel text as non-executable.
Andrew and Linus, could you try this on your G5s? I have tried it
here on a Debian system and a SLES9 system and everything runs fine,
but I haven't been able to try it on YDL, FC or RHEL4.
With this patch we default to executable stack and read-implies-exec
behaviour when there is no PT_GNU_STACK program header entry, or when
there is one and it indicates the stack is executable. For 32-bit
processes, the heap is always executable, because the PLT contains
instructions and it ends up in the bss segment.
