<shaggy@shaggy.austin.ibm.com>
JFS: Avoid segfault when dirty inodes are written on readonly mount
Writes to a device may cause a ->write_inode to be called during a read-only
mount. JFS needs to check for NULL log in jfs_flush_journal.
<shaggy@shaggy.austin.ibm.com>
JFS: Fix broken return code checking in ACL code
<marcel@holtmann.org>
[Bluetooth] Disable credit based flow control by default
The credit based flow control must be disabled by default for compatibility
with Bluetooth 1.0b devices. This patch makes CFC a session attribute,
introduces CFC states and cleans up the CFC logic.
<marcel@holtmann.org>
[Bluetooth] Always use two ISOC URB's
This patch modifies the USB Bluetooth driver to use two ISOC URB's
per RX and TX transfer paths. This is needed for in time transfer
of SCO audio packets over HCI.
<marcel@holtmann.org>
[Bluetooth] Add support for the Digianswer USB devices
The Digianswer USB Bluetooth devices uses a bRequestType of 0x40
for HCI commands, but the Bluetooth specification says that the
correct value is 0x20. This patch sets the needed value according
to the vendor and product id's of the Bluetooth device.
<marcel@holtmann.org>
[Bluetooth] Add support for an old ALPS module
This patch adds the specific vendor and product id's for an old
ALPS module which don't uses the USB Bluetooth class id.
<marcel@holtmann.org>
[Bluetooth] Update HCI security filter
This patch is a very big update to the HCI security filter. It consists
of every forgotten commands/events from Bluetooth 1.1 and also the new
parts from the Bluetooth 1.2 specification.
<marcel@holtmann.org>
[Bluetooth] Support inquiry results with RSSI
The Bluetooth 1.2 specification defines a new event for returning
inquiry results. This patch converts this event into the standard
event and add its information to the inquiry cache.
<marcel@holtmann.org>
[Bluetooth] Remove USB zero packet option
This patch removes the USB zero packet option from the HCI USB
Bluetooth driver, because it is useless. It also corrects the
config name of the SCO audio support.
<marcel@holtmann.org>
[Bluetooth] Support for AVM BlueFRITZ! USB
This adds a driver for the AVM BlueFRITZ! USB devices. The devices
from AVM do not follow the Bluetooth specification part H:2 and thus
they need their own driver.
<marcel@holtmann.org>
[Bluetooth] Correct the module alias for the network family
The module alias for PF_BLUETOOTH was placed in the BNEP module, but it
has to be in the Bluetooth core module.
<marcel@holtmann.org>
[Bluetooth] Add module aliases for the Bluetooth protocols
This patch adds the missing module alias definitions for the various
Bluetooth protocols.
<marcel@holtmann.org>
[Bluetooth] Update the Kconfig entry for the BlueFRITZ! USB driver
The BlueFRITZ! USB driver must use "select" to enable the firmware
loader, because the option "enable" is deprecated.
<marcel@holtmann.org>
[Bluetooth] Add CAPI message transport protocol support
This adds support for the CAPI message transport protocol (CMTP)
to the Bluetooth subsystem.
<marcel@holtmann.org>
[Bluetooth] Add missing maintainer entries for the Bluetooth subsystem
This patch adds the missing maintainer entries for the CAPI message
transport protocol and the BlueFRITZ! USB drivers.
<marcel@holtmann.org>
[Bluetooth] Improve blacklist handling
This patch uses the default ID list to ignore the Broadcom BCM2033 devices
without firmware. If it not handles a device or a interface it now returns
ENODEV to not fill the kernel log with unneeded errors.
<marcel@holtmann.org>
[Bluetooth] Support for Broadcom Blutonium
This adds a driver for the the Broadcom Blutonium USB devices. The devices
with Broadcom chips need a firmware loading sequence before they can work
like any other Bluetooth H:2 USB device.
<jgarzik@redhat.com>
[libata sata_sil] unmask interrupts during initialization
Prudent in general, and needed for Adaptec BIOSes.
<marcel@holtmann.org>
[Bluetooth] Convert interrupt handlers to use irqreturn_t
This patch changes the interrupt routines to make use of the
irqreturn_t return values.
<wim@iguana.be>

runqueue lock held, since those could trigger a deadlock.
<wim@iguana.be>
[WATCHDOG] 2.6.0-rc1 ib700wdt-version-comment.patch
remove "for Linux 2.4.x" in the ib700wdt.c driver
<wim@iguana.be>

[WATCHDOG] 2.6.0-rc1 spelling-fixes-whether.patch
Spelling fixes - whether
<davidm@tiger.hpl.hp.com>
ia64: Skip zero-length resources in PCI root bridge _CRS. This fixes
some ugly messages that used to show up on Tiger and other Intel
boxes:
alloc 0xffffffff-0x0 from PCI mem for PCI Bus 0000:02 failed
alloc 0xffffffff-0x0 from PCI mem for PCI Bus 0000:08 failed

<davidm@tiger.hpl.hp.com>
Many files:
ia64: Cleanup EXPORT_SYMBOL usage
This cleans up the use of EXPORT_SYMBOL in ia64_ksyms.c by
moving most of them to the place where the symbol is defined.
Ideally, only symbols defined in assembler sources should
remain here, but there are some cases where an EXPORT_SYMBOL
is missing outside the arch/ia64 tree. I did not change them
for now. Also, EXPORT_SYMBOL_NOVERS is obsolete.
<akpm@osdl.org>
[WATCHDOG] 2.6.0-rc1 amd7xx_tco.c-nowayout.patch
Fix compile error in amd7xx_tco.c after latest nowayout change
<hch@lst.de>
[PATCH] fix inia100 driver
John W Fort helped me debugging the brown paperbag bugs, the patch below
makes it work.
<mikenc@us.ibm.com>
[PATCH] Initio 9100u
The attached patch adds the cpu_to_le32 calls just in case. It was built
against my previous patch.
<jejb@mulgrave.(none)>
64 bit updates for Workbit NinjaSCSI driver
From: GOTO Masanori <gotom@debian.or.jp>
Thanks for your report. I compiled and exactly I saw some warnings on
amd64 machine. I checked all warnings, and these warnings are
trivial, they can be easily fixed. I attached the patch to fix
warnings. Nsp32 is PCI device driver, so it should also work on amd64
architecture.
<jgarzik@redhat.com>
[libata sata_svr] fix DRV_NAME to reflect actual driver filename
<marchand@kde.org>
[libata sata_sil] add support for adaptec 1210sa, 4-port sii 3114
<greg@kroah.com>
USB: add legotower driver to main usb makefile
<greg@kroah.com>
[PATCH] USB: add a new pl2303 device id.
Thanks to Stefan Verkoyen <stefan.verkoyen@quesd.com> for the information.
<david-b@pacbell.net>
[PATCH] USB: add goku_udc driver (Toshiba TC86C001 USB device)
This patch implements the "USB Gadget" API using the
"Goku-S" (TC86C001) full speed usb device controller.
It's passed testing with Gadget Zero, g_ether (full
CDC Ethernet support), gadgetfs, and most interestingly
Alan Stern's "File Storage Gadget" (FSG, talking to
Linux or Windows as a usb-storage device) to give the
halt processing a good workout. Control-OUT works.
Tested mostly on x86, with reported success on MIPS.
As well as being directly useful with that hardware,
I think this is small and simple enough to be useful
as an example of how to write a USB controller driver.
(There will be many more controller drivers than gadget
drivers, I suspect ...)
Please merge this to the next 2.6 release that takes
new drivers. Corresponding updates for kbuild and the
various gadget drivers will be coming (not in a flood).
<david-b@pacbell.net>
[PATCH] USB: fix kfree in usb-skeleton.c
>> if (dev->bulk_in_buffer != NULL)
>> kfree (dev->bulk_in_buffer);
>

> Yes that one check can go away. Care to send me a patch?
Actually all those checks should go away ...
<greg@kroah.com>
[PATCH] USB: fix bug in bMaxPower sysfs file, it should be * 2
Also cleaned up the string files.
Thanks to Mark Smith for pointing this out.
<greg@kroah.com>
[PATCH] USB: add test for B4000000 to ir-usb driver to fix build issue on some archs
<greg@kroah.com>
USB: add gadget serial driver from Al Borchers

[ARM PATCH] 1712/1: pxa2xx_udc (1/5) add INIT_MACHINE
Patch from David Brownell
This adds a mechanism for a per-machine initcall, one that's
guaranteed to run only to initialize a kernel running on that
specific hardware. It's not strictly necessary, but it does
eliminate the need for certain boilerplate in machine-specific
support, to ensure it's only running on the right hardware:
/* in arch/arm/mach-xxx/MYMACHINE.c */
...
static int __init init_MYMACHINE(void)
{
if (!mach_is_MYMACHINE()) // often forgotten!!
return -EINVAL;
... declare and customize platform devices
...
return 0;
}
arch_initcall(init_MYMACHINE);
An init_MYMACHINE() call still exists, but it'd be declared
as part of the machine definition.
<david-b@net.rmk.(none)>
[ARM PATCH] 1710/1: pxa2xx_udc (2/5) mach-pxa/idp.c uses INIT_MACHINE
Patch from David Brownell
This just makes the IDP initialization code use this initcall, so

[PATCH] qla1280
I am attaching the latest version of the qla1280 driver for inclusion in
the next 2.6.x release. It is mostly based on Christoph's cleanup work
and a couple of changes of my own. I don't know if it is too late for
2.6.1, but otherwise it would be nice to get it into 2.6.2.
I have built and tested this using 2.6.0-test11 on an ia64, but I don't
think there were any major SCSI changes since then.

[PATCH] Call slave_destroy in scsi_alloc_sdev error path
This patch fixes a potential memory leak in scsi_alloc_sdev.
If slave_alloc kmallocs memory and the get_device() (around line 245)
fails then we goto the error path. The error path never calls
slave_destroy.

Sorry Adrian, here is a patch renaming TIMEOUT to TIMEOUT_ERROR. Still
not a good name for the usage in SCSI core, but it does not conflict, and
matches the other names for the IO completion results (SUCCESS, FAILED,
etc., they and others should really be prefixed with at least SCSI).
eata does not use the TIMEOUT it defines, but there are enough defines of
TIMEOUT that it could be a problem in other drivers.
Only compile tested for eata driver.

[PATCH] Kernel oops in 2.6.1 when loading aha152x_cs.ko

[netdrvr 3c527] remove cli/sti
Richard Procter and I worked to remove cli/sti to add proper
SMP support (I did the original stuff and Richard did the
actual current code :)).
Besides that, Richard did a great jog improving the perfomance
of the driver quite a bit:
- Improve mc32_command by 770% (438% non-inlined) over the
semaphore version (at a cost of 1 sem + 2 completions per
driver).
- Removed mutex covering mc32_send_packet
(hard_start_xmit). This lets the interrupt handler operate
concurrently and removes unnecessary locking. It makes the
code only slightly more brittle
Original post:
http://marc.theaimsgroup.com/?l=linux-netdev&m=106438449315202&w=2
Since it didn't apply cleanly against 2.6.0-test6, I forward ported it. Patch attached.

for zx1.

[Bluetooth] Set disconnect timer for incoming ACL links
In general a Bluetooth stack that creates an ACL link should also take

problem is that the Bluetooth specification don't defines an ownership

even if there is no need. To avoid leftover ACL links the disconnect
timer must also be used for incoming connections, but it is set twice
the default disconnect timeout so the other side get enough time to
clean everything by itself.

Thanks for this report; you uncovered a real bug. Actually two real

[PATCH] ia64: move HCDP under serial console #ifdef
Currently you can select HCDP independent of serial console. This
doesn't seem very useful, and makes the setup_serial_hcdp() reference
unresolved if the serial driver is built as a module.
CONFIG_SERIAL_8250_CONSOLE is only selectable if the serial core is
built in (SERIAL_8250=y), so this patch makes sure we don't try to
call setup_serial_hcdp() unless it is actually built in to the kernel.
(I think we should also make HCDP selection dependent on
SERIAL_8250_CONSOLE=y in Kconfig; I'll send a separate patch
for that since it's not ia64-specific.)

<khali@linux-fr.org>
[PATCH] I2C: New parport bus drivers
These are replacements for the i2c-philips-par, i2c-elv and i2c-velleman
drivers, as well as for the i2c-old i2c-parport driver as found under
drivers/media/video in linux 2.4. My reason for writing them, as already
discussed on the sensors and linux-kernel mailing-lists, is that all
these drivers basically do the same thing, so I thought it would be
easier to maintain a single driver instead of four. As Simon Vogl
pointed out that using a direct I/O access (as done in i2c-elv and
i2c-velleman) could be prefered over clean parport access (as done in
i2c-philips-par) on embedded devices, I finally wrote two drivers
instead of one. But both drivers support all devices, it's just a matter
of how they are accessed (and wether the driver depends on the parport
driver).
I made it so that the definition of the adapters (i.e. how to set and
get SDA and SCL, basically) is completely separated from the code
itself. Thus, adding support for a new adapter is simply adding a new
set of data to the definition table, describing how the adapter works,
in a single file.
This means that all simple parallel port adapters are virtually
supported. The i2c-pport driver we have in i2c CVS isn't supported yet
because it works a bit differently, but I believe that extending the
current driver(s) to support it should be possible (although it can be
discussed wether it's worth it).
You'll have to pass the type parameter that is correct for your board:
0 = Philips
2 = Velleman
3 = ELV
4 = ADM evaluation board
I could only test with my ADM eval board, and it worked OK with
both drivers. If they are confirmed to work, we could get rid of all
other parallel port i2c drivers in 2.6.
***
I think we should mark the i2c-philips-par, i2c-elv and
i2c-velleman drivers as "deprecated" in i2c/busses/Kconfig. Is
there a standard way to do so (like there is "&&
EXPERIMENTAL" for new drivers)?
Thanks.

g_NCR5380 - 2.6.0 - problem with reloading module
From: "Randy.Dunlap" <rddunlap@osdl.org>
The problem is that the detect function requests an IO region
of 16 bytes (at least when a command line override parameter is
used) but the release function only tries to release 8 bytes,
and this request isn't done because it doesn't match any allocated
IO region. [NCR53C400 extensions are not enabled, so
NCR5380_region_size is 8, not 16, but the request uses
NCR5380_region_size regardless.]
Fix: save the allocated region size in instance->n_io_ports and release
that size only;

[SERIAL] make HCDP dependent on serial console
Patch from Bjorn Helgaas
I propose the following HCDP Kconfig patch. It makes HCDP
selectable only when serial console has been selected. One
desirable side effect is that both are then available only
when statically compiled in (i.e., not built as a module).
The HCDP support doesn't actually depend on IA64, but I left
that in for now because nobody else implements support for it
and I don't want people confused by a selectable option that
doesn't do anything. Maybe a "depends on EFI" or something
will be useful eventually.

<khali@linux-fr.org>
[PATCH] I2C: speed up eeprom driver by a factor of 4
Basically, I divide the eeprom in 8 32-byte slices. Each of it has a
"valid" boolean (combined together into a bitfield) and a jiffies
counter. Eeprom_update_client() is added a new parameter to specify
which slice to update. Code updated accordingly. Finally, the read
function updates only slices that need to be. The code is heavily
inspired from what was done in the CVS driver, of course.
Three additional notes:
1* This fixes a bug in eeprom_update_client()'s refresh condition. We
used to check jiffies before valid, although jiffies are not defined if
valid isn't true. That was already fixed in our CVS driver but for some
reason the fix did not go into 2.6 yet.
2* This also skips the update if the read if out of bounds. I think this
is the thing to do.
3* It can be discussed wether eeprom_update_client() should take two
slice parameters instead of one (start slice, end slice). This would
make things slightly faster when consecutive slices are requested. Maybe
the code would even be clearer. It wasn't done so far because the CVS
driver wouldn't benefit from it (because the EEPROM's contents are split
over several "output" files in that version of the driver) but I'll
probably give it a try in 2.6.

[PATCH] USB Storage: Old patches (as129 and as141)
There's a couple of old patches floating around still that you might want
to apply. I have reproduced them below.
as129 handles the situation where a command error causes us to do a device
reset, but the SCSI layer times out and aborts the command during the
reset delay. It clears a flag that otherwise will prevent us from sending
the clear-halt messages following the reset.
as141 is the DMA buffer alignment patch. You asked me to remind you about
it eventually. There shouldn't be any harm at all in applying it without
waiting for the corresponding SCSI part of the patch to be applied.
Without that other part, this will essentially do nothing.

[PATCH] USB: EHCI support on MIPS
From Darwin Rambo, <drambo@broadcom.com>
These get rid of 8 and 16 byte PCI access, which don't work
on some MIPS platforms.
<david-b@pacbell.net>
[PATCH] USB: high speed iso maxpacket is 1024 not 1023
Someone sent this around mixed with an EHCI patch which should not
be applied (there's a different patch on the way). I lost their
name, sorry. It lets 1024 byte ISO packets be used.
<david-b@pacbell.net>
[PATCH] USB: ehci update: 1/3, misc
This is minor "obvious" fixes plus two tweaks to help later
patches:
- Interrupt QH has a link to the device, needed to implement
schedule trees (like OHCI does today) that are TT-aware
(essential for most keyboards and mice).
- Export the macros that do high bandwidth packetsize stuff.
They're also needed for high bandwidth ISO transfers.
It also morphs some existing "too much debug info" urb tracing
so it's kicked in by a manual #define EHCI_URB_TRACE. If some
generic version of that gets added to usbcore, this sort
of debug code can vanish (from all hcds).
<david-b@pacbell.net>
[PATCH] USB: ehci update: 2/3, microframe scanning
This patch is needed to make high bandwidth ISO streams behave,
but could resolve some other scanning glitches. Current users
of periodic transfers (interrupt transfer modes for hubs, mice,
and keyboards) shouldn't even notice this change.
It makes the periodic schedule scan handle cases where a given
frame's schedule slot reports completions in several different
microframes. So far that's been uncommon, but it's typical
for high bandwidth iso (or even with busier interrupt trees than
this driver has supported yet).
It also starts to remove the assumption that each ITD only uses
one microframe; but most of those changes are in the next patch.
And it fixes a bug where some status bits were mis-interpreted as
significant bits in the ITD transfer length.
<david-b@pacbell.net>
[PATCH] USB: ehci update: 3/3, highspeed iso rewrite
This is an updated version of a patch submitted to me from
Michal Sojka <sojkam1@fel.cvut.cz>, basically providing a
much-needed rewrite of the highspeed ISO support. I updated
the scheduling and made it a closer match to how OHCI works;
and also tested it a bunch.
So far it seems most of the requests for highspeed ISO support
have been for realtime data collection -- custom apps, nothing
a mainstream kernel would ship with. The USB Video class is
now defined; highspeed video will also need these updates.
Key changes:
- Define an "iso_stream" head for iso endpoints. This acts
enough like a QH that endpoint_disable() works. It holds the
queue of ITDs, and the endpoint's current schedule state.
And it's easy to find (spinlocked array access), no search.
- Uses a temporary "itd_sched" while submitting each URB, with
not-yet-linked ITDs and request-specific metadata. There's
a per-stream cache of ITDs, so resubmitting ISO urbs (to
achieve a "ring" of transfers) is typically cheap.
- Scheduling for most URBs is almost a NOP: just a sanity
check to make sure there's no need to reschedule, and then
just link into the schedule at the current schedule slot.
(The previous code was a gross hack that didn't even work
reasonably with more than two URBs queued.)
- Is a reasonable model to use with full speed ISO transfers.
(They need additional TT scheduling hooks, most of which
are already written but not merged.)
- Handles several cases the previous code didn't, including
high bandwidth transfers (loads up to 24 MByte/sec)
- Has had more testing than the old code, including 20+ hour
successful IN+OUT runs, more varied transfer intervals and
maxpacket sizes. (Using net2280 and a gadgetfs driver.)
So it's worth replacing the existing code with this; there
aren't too many rough edges, and it's much more fixable than
the previous version.
p.s. Many thanks, Michal!

[PATCH] USB Storage: Remove non s-g pathway from subdriver READ/WRITE
This patch does what you suggested. The read/write routines from the
updated subdrivers are changed so they don't bother to differentiate
between transfers that do or do not use scatter-gather. The low-level
usb_stor_access_xfer_buf routine will Do The Right Thing regardless, and
there probably won't ever be more than a few non s-g calls. (What about
filesystem I/O requests to access metadata?)
It turns out that in addition to removing some comments and a few tests,
this change allowed me to remove the buffer and use_sg arguments passed to
the read/write routines as well. So the simplification ended up being a
bit bigger than I expected.
While writing this patch, I noticed spots in several drivers that still
need to be changed -- they slipped past me before. These drivers handle
things like READ-CAPACITY or REQUEST-SENSE by copying the data directly to
srb->request_buffer, which is obviously wrong if s-g is being used. I'll
send in changes next week that convert them to use the
usb_stor_set_xfer_buf function. Like you said, it's going to be handy in
more places than originally intended!

number of things have piled up, and Linus didn't want any of this during
feature freeze time). All of these changes are specific to the SH platform,
and as such, shouldn't effect any other platforms.

[PATCH] kyrofb support
From: Paul Mundt <lethal@linux-sh.org>
This patch adds support for the Kyro graphics boards (STG4000/PowerVR
3/etc= .) to 2.6. This is a direct port and substantial cleanup / rewrite
of the 2.4 driver that's available in the sh64 tree at linux-sh.bkbits.net.
Some of the overlay code and the STG4000 bits are still a bit ugly, so be
forewarned.

[PATCH] loop: fix hard sector size
From: Ben Slusky <sluskyb@paranoiacs.org>
We need to set the hardsect_size of the loop device to that of the real
device.
The loop device advertises a block size of 1024 even when configured over a
cdrom.
When burning a ext2 on a cd, and mounting it directly, I get:
blocksize=2048;
when I losetup /dev/loop0 /dev/cdrom, and then try to mount, I get:
blocksize=1024; and then misaligned transfer; this results in not being able
to read the superblock.
The loop device should be changed to export the same blocksize of the
underlying device

[PATCH] bdev: open() changes
The first of a series which move us toward blockdev hotplug support. After
these we have achieved the following:
a) For "normal" (not bdevfs) inodes of block devices we never look at
->i_mapping.
b) For the same inodes we only look at ->i_bdev in bd_acquire() where it's
used only as "here's what we'd found the last time" sort of cached value.
If it's NULL, we just recalculate it.
c) Lots of messy expressions had been trimmed down, while we are at it.
(a) and (b) allow us to start doing proper block hotplug - we can destroy the
association between inode and bdev at any time, unhash bdev in question and
have new open() do everything from scratch, without waiting for old opened
files to close. The goal is to be able to say "revoke everything over that
gendisk"/"revoke that partition" and have it do the right thing.
This patch:
Where the old code called (block device) ->open(inode, file), use
->open(inode->i_bdev->bd_inode, file). Changes in drivers:
* none to those that only used inode->i_bdev and inode->i_rdev in their
->open() (bdev->bd_inode->i_bdev == bdev, so we are OK)
* floppy.c and floppy98.c used to call permission(inode, ...) in
floppy_open(). Switched to permission(file->f_dentry->d_inode, ...)
<akpm@osdl.org>
[PATCH] bdev: blkdev_put() cleanup
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
Trivial cleanup in blkdev_put() - replace bdev->bd_inode->i_bdev with bdev.
<akpm@osdl.org>
[PATCH] bdev: presto conversion
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
presto_journal_close() switched to passing struct presto_file_data * instead
of bogus struct file *. The only field of struct file we used to look at was
file->private_data and most of the callers allocated on-stack struct file,
assigned file.private_data and passed the sucker to presto_journal_close().
Idiocy removed.
Looks like they started with case where the data they wanted all along was,
indeed, in ->private_data of already available struct file, so they just
passed pointer to struct file. And when they found that they need to call it
in other places where there was no such struct file, they'd done it the dumb
way instead of fixing the prototype...
<akpm@osdl.org>
[PATCH] bdev: add file.f_mapping
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
New field of struct file - ->f_mapping. We maintain the following:
file->f_dentry->d_inode->i_mapping == file->f_mapping for all opened files.
<akpm@osdl.org>
[PATCH] bdev: switch to f_mapping
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
A lot of places used to use ->f_dentry->d_inode->i_mapping all over the
place. Replaced with use of ->f_mapping. For now - just the places where we
literally could do search-and-replace.
<akpm@osdl.org>
[PATCH] bdev: use correct mapping's i_sem
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
In a bunch of places we used file->f_dentry->d_inode->i_sem to protect
fdatasync et.al. Replaced with corrent file->f_mapping->host->i_sem - the
object we are protecting is address_space, so we want an exclusion that would
work for redirected ->i_mapping. For normal files (not coda, not bdev) it's
all the same, of course - there we have
file->f_mapping->host == file->f_dentry->d_inode
and change above is an equivalent transfromation.
<akpm@osdl.org>
[PATCH] bdev: move i_mapping -> f_mapping conversions
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
More uses of ->i_mapping switched to uses of ->f_mapping - stuff that was not
caught by the earlier f_mapping conversion.
<akpm@osdl.org>
[PATCH] bdev: generic_osync_inode() conversion
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
generic_osync_inode() got an extra argument - mapping and doesn't calculate
inode->i_mapping anymore. Callers updated and switched to use of
->f_mapping.
<akpm@osdl.org>
[PATCH] bdev: bd_acquire() cleanup
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
bd_acquire() made static, switched to returning the block_device it had
found. Callers updated.
<akpm@osdl.org>
[PATCH] bdev: generic_write_checks() cleanup
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
generic_write_checks() had lost the first argument (inode) - it can be
calculated from the second one (file).
<akpm@osdl.org>
[PATCH] bdev: add I_BDEV()
From: viro@parcelfarce.linux.theplanet.co.uk <viro@parcelfarce.linux.theplanet.co.uk>
For bdevfs inodes (ones created along with struct block_device by
fs/block_dev.c) we have inode->i_bdev equal to &BDEV_I(inode)->bdev (i.e.
it's at the constant offset from inode). New helper added for such inodes
(I_BDEV(inode)). A bunch of places (mostly in block_dev.c) switched to use
of that helper. A bunch of places that used
file->f_dentry->d_inode->i_bdev->bd_inode
switched to
file->f_mapping->host
- those expressions are equal whenever the former is valid.
<akpm@osdl.org>
[PATCH] cramfs: use pagecache better
From: viro@parcelfarce.linux.theplanet.co.uk
Patch switches cramfs_read() to direct use of pagecache and
eliminates all messing with buffer_heads. Fixes the interaction with
ramdisk (there set_blocksize() simply killed the ramdisk contents) and
gets code less brittle overall.
<akpm@osdl.org>
[PATCH] raw.c refcounting fix
From: viro@parcelfarce.linux.theplanet.co.uk
raw.c has a refcounting bug (patch attached).
As for the theory... If you have a pathname - use filp_open() or
open_bdev_excl() and be done with that. bdget() et.al. are OK only if you
really have nothing better than device number and that's a situation that
should be avoided unless you really have no choice.
Said that, we have the following primitives:
* lookup_bdev(): takes a pathname, returns a reference to block_device.
* bdget(): takes a number, returns a reference to block_device.
* blkdev_get(): takes a reference to block_device and opens it. If open
fails - drops the reference to block_device passed to it.
* blkdev_put(): takes a reference to block_device and closes it. The
reference is dropped.
* bdput(): drops a reference to block_device.
Note that behaviour of blkdev_get() and blkdev_put() is such that it makes
for minimal cleanup code.
bd_claim()/bd_release() is the exclusion mechanism - that's what mount,
swapon, open with O_EXCL, etc. are using to avoid stepping on each others
toes. bd_claim() claims bdev for given owner; if it's already owned and
not by the same owner you'll get -EBUSY. bd_release() reverts the effect
of bd_claim(). Note that if you claim the thing N times (with the same
owner, obviously), you'll need N bd_release() before it stops being owned.
raw.c grabbed a reference to bdev only after blkdev_get(). If blkdev_get()
failed (e.g. media being absent), you've got an unbalanced bdput().

[PATCH] ppc64: setup_cpu must be called on boot cpu
From: Anton Blanchard <anton@samba.org>
setup_cpu was being called for the boot cpu after all other cpus had been
spun up. The init thread can sleep during secondary cpu spinup (eg migration
thread init) and sometimes the init thread would switch to another cpu at
this time. The end result was setup_cpu was called twice on one cpu and
never on the boot cpu.
The original fix called setup_cpu on the boot cpu before all others but that
wont work for G5, so we now use cpu affinity calls to enforce it.

[PATCH] Fix IO scheduler regression
From: Nick Piggin <piggin@cyberone.com.au>
Randy has just reported that this fixes up his regression. Its now as good
as test5 in his tests with this patch. He is also seeing quite large
increases (above test5) when IO scheduler barriers are disabled (this patch
doesn't do that). Perhaps something is using them too liberally.
Anyway, this reverts AS back to defaulting to not anticipate IO for a
program that submits its first request (this really hurts find | xargs grep
sort of things). I am working on something to fix this up properly. That
can go in after 2.6.0 anyway.

problem too.

[PATCH] AS: new process estimation
From: Nick Piggin <piggin@cyberone.com.au>
This one gathers better statistics about the new process problem. It
improves estimation for initial process IO. That is, better calculations
for whether it will be worth waiting after a process submits its first
read.
This is done with a per queue average thinktime and seek time for a second
read submitted from a process.
When combined with 3/3, numbers are around the same as mm1 for most long
lived tasks, but much better for things like the top 4 benchmarks.
Probably wants rwhron and the OSDL database guys to give it some testing.

[PATCH] AS: thinktime improvement
From: Nick Piggin <piggin@cyberone.com.au>
Sometimes a processes thinktime shouldn't be measured on how soon it
submits its next request, but how soon any close request is submitted.
Some processes, such as those in make -j, find | xargs blah, etc. Should be
waited upon even if they never submit another request, because they work with
cooperating or child processes. This helps to take that into account.

[PATCH] AS tuning
From: Nick Piggin <piggin@cyberone.com.au>
The big regression from deadline is tiobench random reads with TCQ disks,
however it is present in -linus as well, and would have been since day 1 of
AS, but nobody has complained too loudly.
http://developer.osdl.org/judith/tiobench/4CPU/rr.html
This problem is probably a distilation of what causes lower database
throughput, because I have only ever seen it with TCQ drives, and pgbench
and OraSim are actually getting higher throughput here with a non TCQ
drive.
That is not to say that TCQ is useless, it obviously can provide a very
real and significant boost. What I might do in the (near) future is get AS
to detect TCQ and turn itself off indefinitely unless/until the a sysfs
flag is set, and default that flag to off.
This patch changes the AS tunables a bit to be more on par with deadline. It
lowers the threshold for random reading processes to be considered unsuitable
for anticipation, and it slightly rearranges and comments the "cooperative
seek distance" logic.
With this patch, AS is now very competitive with deadline on the single IDE
and SCSI (non TCQ) disks here. In fact, I don't have any regressions
anywhere. Even when TCQ is on, although throughput can be lower, AS still
has benefits because of its much better read vs write latency and general
tendancy to keep number of outstanding tags smaller.

[PATCH] ATAPI MO drive support
From: Pascal Schmidt <der.eremit@email.de>
The below patch is needed to support ATAPI MO drives in 2.6. ide-scsi

running the MO drive. Without this, there is no way to write to an
ATAPI MO drive.
This patch has been discussed with Linus and Jens already around test9
time and it was agreed this is the right way to go about it. I have
rediffed it against 2.6.0. Compiles, runs, works just fine for me.

[PATCH] Make ppp_async callable from hard interrupt
From: Paul Mackerras <paulus@samba.org>
Since there are serial drivers (particularly the USB serial driver) that
call the line discipline receive_buf and write_wakeup routines at hard
interrupt level, I have changed the ppp_async code to cope with that. It
now uses a tasklet so that it calls the generic PPP code at soft interrupt
level even if its receive_buf and write_wakeup entries are called at hard
interrupt level.
This patch has been lightly tested here with a keyspan USB serial adaptor
and also with the built-in modem on my tibook, which uses the pmac_zilog
driver (which hooks into the drivers/serial infrastructure).

[PATCH] make try_to_free_pages walk zonelist
From: Rik van Riel <riel@surriel.com>
In 2.6.0 both __alloc_pages() and the corresponding wakeup_kswapd()s walk
all zones in the zone list, possibly spanning multiple nodes in a low numa
factor system like AMD64.
Also, if lower_zone_protection is set in /proc, then it may be possible
that kswapd never cleans out data in zones further down the zonelist and
try_to_free_pages needs to do that.
However, in 2.6.0 try_to_free_pages() only frees pages in the pgdat the
first zone in the zonelist belongs to.
This is probably the wrong behaviour, since both the page allocator and the
kswapd wakeup free things from all zones on the zonelist. The following
patch makes try_to_free_pages() consistent with the allocator, by passing
the zonelist as an argument and freeing pages from all zones in the list.
I do not have any numa systems myself, so I have only tested it on my own
little smp box. Testing on NUMA systems may be useful, though the patch
really only should have an impact in those rare cases where kswapd can't
keep up with allocations...
As a side effect, the patch shrinks the kernel by 2 lines and replaces some
subtle magic by a simpler array walk.

[PATCH] kill_fasync speedup
From: Manfred Spraul <manfred@colorfullife.com>
fasync_helper and kill_fasync are helpers for managing F_SETFL fcntl
calls that change FASYNC and sending the necessary signals. The locking
uses one global rwlock that's acquired for read in all kill_fasync
calls, and that causes cache line trashing. This is not necessary: if
the fasync list is empty, then there is no need to acquire the rwlock.
Tests with reaim on a 4-way pIII on STP showed an 80% reduction of the
time within kill_fasync.

[PATCH] O21 for interactivity 2.6.0
From: Con Kolivas <kernel@kolivas.org>
A non-critical corner case has come up for interactivity that I believe needs
to be addressed. It is only extensive testing and examination that revealed
this, as this interactivity work is in maintenance mode.
Description:
It is possible for a highly interactive task (like X) to cause large
latencies in tasks that are less 'niced' (eg negative nice number
compared to X which should normally run at nice 0) if they are fully
cpu bound. This occurs due to expiration of the cpu bound tasks.
This patch addresses this by not reinserting interactive tasks into
the active array if there is a better static priority task running but
has been placed on the expired array. This causes a substantial
reduction in the maximum scheduling latency a task with a less nice
value can have.
This also has the positive side effect of maintaining better cpu%
proportions for tasks of different nice levels.
Testers will only be able to discern a difference with highly cpu bound tasks
of normal scheduling policy at different nice levels. Test cases are doing
something cpu intensive relatively -niced in the presence of an interactive
load (eg capturing and encoding video at nice -10 while using X nice 0, or
something nice 0 vs nice +10) and so on. Because of the crossover of 10
'nice' levels of dynamic priorities between interactive and cpu bound tasks
this patch will have a more noticable effect as the nice difference is
greater, especially 11 or more.

[PATCH] Make for_each_cpu() Iterator More Friendly
From: Rusty Russell <rusty@rustcorp.com.au>
Anton: breaks PPC64, as it needs cpu_possible_mask, but fix is already
in Ameslab tree.
The for_each_cpu() and for_each_online_cpu() iterators take a mask, and
noone uses them that way (except for arch/i386/mach-voyager, which uses
for_each_cpu(cpu_online_mask). Make them more usable iterators, by
dropping the "mask" arg.
This requires that archs provide a cpu_possible_mask: most do, but PPC64
doesn't, so it is broken by this patch. The other archs use a #define to
define it in asm/smp.h.
Most places doing loops over cpus testing for cpu_online() should use
for_each_cpu: it is synonymous at the moment, but with the CPU hotplug
patch the difference becomes important.
Followup patches will convert users.

Reindent the trident OSS sound driver
<akpm@osdl.org>
[PATCH] trident OSS sound driver fixes
From: Muli Ben-Yehuda <mulix@mulix.org>
- switch lock_set_fmt() and unlock_set_fmt() from macros to inline
functions. Macros that call return() are EVIL.
- simplify lock_set_fmt() and implement it via test_and_set_bit() rather
than a spinlock protecting an int.
- fix a bug wherein we would do an up() on a semaphore that hasn't been
down()ed if a signal happened after timeout in trident_write().
- fix a bug where we would not release the open_sem on OOM.
- make the arguments for prog_dmabuf clearer (int -> enum), and add two
wrapper functions around it, one for record and one for playback.
- fix a bug where we would call VALIDATE_STATE after lock_kernel(). Since
VALIDATE_STATE does 'return' if validation fails, bad things can happen.
Thanks to Dawson Engler <engler@stanford.edu> and the Stanford checker for
spotting.
- remove the calls to lock_kernel() from trident_release() and
trident_mmap(). trident_release() appears to be covered by the open_sem,
and trident_mmap() is covered by state->sem.

[PATCH] selinux: Add resource limit control
From: James Morris <jmorris@redhat.com>
This patch adds controls to the SELinux module over the setting and
inheritance of resource limits. With these controls, the ability to set
hard limits can be limited to specific processes such as login, and when an
untrusted process invokes a more trusted program, soft limits can be reset,
thereby avoiding failures in the trusted program due to malicious setting
of the soft limit by the untrusted process. Roland McGrath provided input
and feedback on the patch, which was implemented by Stephen Smalley
<sds@epoch.ncsc.mil>.

[PATCH] selinux: add netif controls
From: James Morris <jmorris@redhat.com>
This patch adds netif access controls for SELinux, which allows network
traffic to be controlled on the basis of associated network interface.
Similar functionality was present in earlier SELinux implementations; this
is a rework within the constraints of the LSM hooks present in the mainline
kernel.
<akpm@osdl.org>
[PATCH] selinux: Add node controls
From: James Morris <jmorris@redhat.com>

SELinux implementations; this is a rework within the constraints of the LSM
hooks present in the mainline kernel.

[PATCH] selinux: Add SO_PEERSEC socket option and getpeersec LSM hook.

The purpose of this is to allow applications to obtain each others security
credentials, analagously to the existing SO_PEERCRED option.
Examples of use are Security Enhanced D-BUS and Security Enhanced X.
This patch was previously approved in principle by David, and has been
updated with feedback from Chris Wright and extended to cover all

[PATCH] selinux: improve skb audit logging
From: James Morris <jmorris@redhat.com>
This patch is a rework of the skb audit logging code in SELinux. Rather
than relying on skb header pointers, it parses the skb for specific
protocols (TCP and UDP for IPv4 at this stage). This is safer for the case
of locally generated raw packets, which can be malformed. It also now
takes fragmented skbs into account. The new code allows the caller to
parse the skb so that parsed information can be more readily re-used.
<akpm@osdl.org>
[PATCH] Add SEND_MSG and RECV_MSG controls
From: James Morris <jmorris@redhat.com>
This patch implements two new access controls for SELinux: SEND_MSG and
RECV_MSG, providing mediation of network packets based on destination port
(IPv4 only at this stage).

[PATCH] NFS: fix bogus setattr calls
From: Trond Myklebust <trond.myklebust@fys.uio.no>
If users set the execute bit on a file, and then write to it,
remove_suid() causes a flood of SETATTR calls (one per write() syscall)
with no arguments to be sent down the wire.
The server will in any case clear the suid bit itself without any
prompting from us, so the following patch simply filters away all
SETATTR requests with empty or unsupported ia_valid fields.
<akpm@osdl.org>
[PATCH] nfs: Optimize away unnecessary NFSv3 COMMIT calls.
Currently, when calling nfs_commit_file(), we check the range argument,
and only commit NFS write requests that fall within the given range.
This is silly, since all servers use fsync(), to honour a COMMIT call,
and so will sync all pending writes to stable storage.
The following patch ensures that if at least one NFS write falls within
the range specified by the call to nfs_commit_file(), then we commit all
outstanding writes on that file.
This fixes a sometimes severe inefficiency when combining reads and
writes: nfs_wb_page() is used to clear out writes prior to scheduling a
read(), and can end up calling COMMIT for each page to be read.

[PATCH] s390: 32 bit ioctl emulation fixes.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
- audit all 32 bit pointer accesses and make them use compat_ioctl(),
because of the necessary conversion on s390
- introduce ULONG_IOCTL() which is used instead of COMPATIBLE_IOCTL()
for all ioctls that have their argument encoded in 'arg' instead
of the memory pointed to by arg. Same reason as above.

CONFIG_BLK_DEV_DM e.g. was insufficient).
- comment out COMPATIBLE_IOCTL(SIOCSIFBR) and
COMPATIBLE_IOCTL(SIOCGIFBR), they appear to require a handler
- implement copy_in_user for s390, as needed for many handlers in
fs/compat_ioctl.c
- get rid of all duplicate stuff in arch/s390/kernel/compat_ioctl.c
that is also in fs/compat_ioctl.c

[PATCH] s390: tlb flush optimization.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
On the s/390 architecture we still have the issue with tlb flushing and the
ipte instruction. We can optimize the tlb flushing a lot with some minor
interface changes between the arch backend and the memory management core.
In the end the whole thing is about the Invalidate Page Table Entry (ipte)
instruction. The instruction sets the invalid bit in the pte and removes the
tlb for the page on all cpus for the virtual to physical mapping of the page
in a particular address space. The nice thing is that only the tlb for this
page gets removed, all the other tlbs stay valid. The reason we can't use
ipte to implement flush_tlb_page() is one of the requirements of the
instruction: the pte that should get flushed needs to be *valid*.
I'd like to add the following four functions to the mm interface:
* ptep_establish: Establish a new mapping. This sets a pte entry to a
page table and flushes the tlb of the old entry on all cpus if it
exists. This is more or less what establish_pte in mm/memory.c does
right now but without the update_mmu_cache call.
* ptep_test_and_clear_and_flush_young. Do what ptep_test_and_clear_young
does and flush the tlb.
* ptep_test_and_clear_and_flush_dirty. Do what ptep_test_and_clear_dirty
does and flush the tlb.
* ptep_get_and_clear_and_flush: Do what ptep_get_and_clear does and
flush the tlb.
The s/390 specific functions in include/pgtable.h define their own optimized
version of these four functions by use of the ipte.
I avoid the definition of these function for every architecture I added them
to include/asm-generic/pgtable.h. Since i386/x86 and others don't include
this header yet and define their own version of the functions found there I
#ifdef'd all functions in include/asm-generic/pgtable.h to be able to pick
the ones that are needed for each architecture (see patch for details).
With the new functions in place it is easy to do the optimization, e.g. the
sequence
ptep_get_and_clear(ptep);
flush_tlb_page(vma, address);
gets replace by
ptep_get_and_clear_and_flush(vma, address, ptep);
The old sequence still works but it is suboptimal on s/390.
<akpm@osdl.org>
[PATCH] s390: physical dirty/referenced bits.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
this is another s/390 related mm patch. It introduces the concept of
physical dirty and referenced bits into the common mm code. I always
had the nagging feeling that the pte functions for setting/clearing
the dirty and referenced bits are not appropriate for s/390. It works
but it is a bit of a hack.
After the wake of rmap it is now possible to put a much better solution
into place. The idea is simple: since there are not dirty/referenced
bits in the pte make these function nops on s/390 and add operations
on the physical page to the appropriate places. For the referenced bit
this is the page_referenced() function. For the dirty bit there are
two relevant spots: in page_remove_rmap after the last user of the
page removed its reverse mapping and in try_to_unmap after the last
user was unmapped. There are two new functions to accomplish this:
* page_test_and_clear_dirty: Test and clear the dirty bit of a
physical page. This function is analog to ptep_test_and_clear_dirty
but gets a struct page as argument instead of a pte_t pointer.
* page_test_and_clear_young: Test and clear the referenced bit
of a physical page. This function is analog to ptep_test_and_clear_young
but gets a struct page as argument instead of a pte_t pointer.
Its pretty straightforward and with it the s/390 mm makes much more
sense. You'll need the tls flush optimization patch for the patch.

[PATCH] s390: tlb flush race.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
I think I found a potential race in install_page/install_file_pte. The
inline function zap_pte releases pages by calling page_remove_rmap and
page_cache_release. If this was the last user of a page it can get
purged from the page cache and then get immediatly reused. But there
might still be a tlb for this page on another cpu. The tlb is removed
in the callers of zap_pte, install_page and install_file_pte, but this
is too late. I admit that its a very unlikely race but never the less..
I fixed this by using the new ptep_clear_flush function that is introduced
with the tlb flush optimization patch for s/390.
<akpm@osdl.org>
[PATCH] s390: rmap optimization.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
while working on my mm patch for s390 I played with rmap a bit, adding
BUG statements and the like. While doing so I noticed some room for
improvement in rmap. Its minor stuff but anyway...
The first observation is that the pte chain array doesn't have holes,
meaning that from the pte_chain_idx() of the first array every slot of
all following pte chain arrays are full. That is there can't be NULL
pointers. The "if (!pte_paddr)" check in try_to_unmap() can be removed
and if the loop in page_referenced() is started from pte_chain_idx(pc)
then the "if (!pte_paddr)" in page_referenced() can be removed as well.
The second observation is that the first pte array of a pte chain has
at least one entry. Empty pte chain arrays are always freed immediatly
after the last entry was removed. Because of that victim_i can be
calculated in a simpler way. Instead of setting victim_i to -1 and then
check in each loop iteration against -1 victim_i can just be set to
the pte_chain_idx of the first pte chain array.

[PATCH] s390: superflous flush_tlb_range calls.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
while searching for a s390 tlb flush problem I noticed some superflous tlb
flushes. One in zeromap_page_range, one in remap_page_range, and another one
in filemap_sync. The patch just adds comments but I think these three
flush_tlb_range calls can be removed.

[PATCH] s390: endless loop in follow_page.
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
Fix endless loop in get_user_pages() on s390. It happens only on s/390
because pte_dirty always returns 0. For all other architectures this is an
optimization.
In the case of "write && !pte_dirty(pte)" follow_page() returns NULL. On all
architectures except s390 handle_pte_fault() will then create a pte with
pte_dirty(pte)==1 because write_access==1. In the following, second call to
follow_page() all is fine. With the physical dirty bit patch pte_dirty() is
always 0 for s/390 because the dirty bit doesn't live in the pte.

[PATCH] const vs. __attribute__((const)) confusion
From: "H. Peter Anvin" <hpa@zytor.com>
Declaring a function to return a const scalar value is pretty meaningless.
These functions are really trying to say that they don't alter any external
state.
Fix that up by using __attribute__((const)), if the compiler supports that.

[PATCH] v4l: videodev update
From: Gerd Knorr <kraxel@bytesex.org>
This patch fixes some v4l2 ioctl #defines which have wrong _IO* macros. It

binary backward compatibility.
<akpm@osdl.org>
[PATCH] v4l: v4l2 update
From: Gerd Knorr <kraxel@bytesex.org>
This patch is a v4l2 update. Changes:
* added new ioctls (VIDIOC_G_PRIORITY, VIDIOC_S_PRIORITY) to give v4l apps
priorities for tuning and other controls. Main purpose is that backgrounds
applictions like nxtvepg which are fishing informations from /dev/vbi
(teletext, epg, ...) can run at lower priority than interactive tv apps and
thus the user isn't annonyed with unexpected channel switches.
* add a set of helper functions to handle priorities to the v4l2-common
module.
* minor fixes in the v4l1-compat module.
* minor header file fixes.

[PATCH] v4l: bttv driver update
From: Gerd Knorr <kraxel@bytesex.org>
bttv driver update. Changes:
(1) Added a new, sysfs-based interface to allow access to the bt878 gpio
lines from other kernel modules (new bttv-gpio.c file), which fixes alot
of problems the old interface has (which still is in bttv-if.c, to be
removed in 2.7).
(2) moved the i2c code from bttv-if.c to bttv-i2c.c.
(3) created a new "struct bttv_core" and moved some of the entries from
"struct bttv" to the new one. This is needed for (1) and makes the patch
pretty big, althrough there is no actual code changes.
(4) first cut for suspend support (S1 works for me).
(5) usual batch of new/updated tv card list entries.
(6) minor fixes.

I replaced all dependancies on algos with dependancies on

comment. I think it's more logical that way. Without it, the user could
get the message he/she needs I2C, go to enable it, come back and still
not see the option.

The new driver for Eicon ISDN cards is in drivers/isdn/hardware/eicon.
The old driver is still in drivers/isdn/eicon and I would like to remove
this old driver from the 2.6 kernels.

[PATCH] Remove redundant code in workqueue.c
From: Rusty Russell <rusty@rustcorp.com.au>
It turns out that run_workqueue never has signal_pending(), since setting
the handler to SIG_IGN means "don't make zombies, I'm ignoring them". Fix
the comment, don't allow the signal, and remove the unused waitpid loop.
This also allows simpler conversion of workueues to the kthread mechanism,
which uses signals to indicate it's time to stop.

[PATCH] Optimize proc_pid_lookup
From: Manfred Spraul <manfred@colorfullife.com>
readdir on /proc has two problems: reading all entries is O(N^2), and
entries are overlooked if tasks die in the middle of readdir: the readdir
implementation remembers the offset into the task list, and if a task
(actually: process) that was returned by previous readdir calls exits, then
a random entry is dropped.
The attached patch fixes the O(N^2) by using f_version to store the pid of
the task that should be returned next. This speeds up reading /proc to
O(N). Additionally, it mitigates the effects of dying tasks: Tasks are
skipped only if the task whose pid is stored in f_version exits, all other
task deaths have no effect. Unfortunately the code has a bad worst case
behavior: if the targeted task exits and a new task with the same pid is
created, then all entries in the task list between old and new position are
dropped. This should be rare.
<akpm@osdl.org>
[PATCH] clarify meaning of bio fields in the end_io function
From: Christophe Saout <christophe@saout.de>
The intent of these are to clarify the meaning of the bio fields in the
bi_end_io function (since we are already mostly there). After these small
modifications bio->bi_idx and the corresponding bio_iovec(bio)->bv_offset
point to the beginning of the completed data, together with the nr_bytes
argument you know exactly what data was finished, e.g. when you can't
track it otherwise (or it would be unnecessary expensive). Apart from that
it's a nice-to-have.
The first mini-patch moves the update of bio_iovec(bio)->bv_offset and
->bv_len after the call of bi_end_io where bi_idx gets updated so they get
updated together. Ok with Jens.
The second part of the patch modifies the multwrite hack in PIO non-
taskfile ide disk code. It modifies the bi_idx field to walk the bios and
doesn't reset it correctly before ending the request. The patch uses the
segment counter in the request field to correctly restore the bi_idx field
before ending the request. Can't possibly break anything since it's
working on the local request copy ("scratchpad") anyway. Also does this in
legacy/pdc4030.c (similar code). The code modified here is going to die
anyway any trying to fix it would be too invasive. Ok with Bartlomiej.

[PATCH] Simplify node/zone field in page->flags
From: Matthew Dobson <colpatch@us.ibm.com>
This patch does the following:
1) Rename ZONE_SHIFT to NODEZONE_SHIFT. This value is the number
of bits to shift page->flags to get the node/zone part of the
bitfield.
2) Add a macro called NODEZONE which takes a node number and zone number
and returns a 'nodezone', a bitshifted composition of the two.
3) Create page_zonenum & page_nodenum, inline functions to return the
node/zone a page belongs to with some simple bit twiddling, no
pointer dereferences necessary.
4) Modify page_zone() and set_page_zone() to use the new NODEZONE_SHIFT.
5) Modify memmap_init_zone() & free_area_init_core() to use the new
NODEZONE macros.
6) Fix up some comments to reflect the above changes.

[PATCH] Relocation overflow with modules on Alpha
From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>
Larger modules fail to load with the message "Relocation overflow vs

This failure happens with GPRELHIGH relocation, which is *signed* short,

[PATCH] Fix Documentation/SubmittingPatches to use -p
From: "Martin J. Bligh" <mbligh@aracnet.com>
Patches are a damned sight easier to read if people use the '-p'
option to diff ... this generates output that looks like this:
"@@ -323,6 +323,7 @@ void put_dirty_page(struct task_struct *"
for each block. This patch simply adds that to the documentation
file, in the hope of steering new users in the right direction.

[PATCH] Kconfig: use range for NR_CPUS
From: Adrian Bunk <bunk@fs.tum.de>
The 2.6 Kconfig language allows to set the range for integer questions.
The patch below adds a range line on all architectures that have a
NR_CPUS question except ia64.
The help text on ia64 didn't suggest any values. Could someone tell the
correct values for ia64 (and if it's only a minimum value of 2)?

[PATCH] bio documentation update
From: Jens Axboe <axboe@suse.de>

least one page to an empty bio.

[PATCH] readahead part-backout
From: Ram Pai <linuxram@us.ibm.com>
Remove the up-front readahead code from the core pagecache read
function: it's really bad for large reads.
<akpm@osdl.org>
[PATCH] revert lazy readahead
From: Trond Myklebust <trond.myklebust@fys.uio.no>
The following reversion is what fixes my regression. That puts the
sequential read numbers back to the 2.6.0 values of ~140MB/sec (from the
current 2.6.1 values of 14MB/second)...
We were triggering I/O of the `ahead' when we hit the last page in the
`current' window. That's bad because it gives no pipelining at all.
So go back to full pipelining.
It's not at all clear why this change made a 10x difference in NFS
throughput.

[PATCH] kconfig: fix menuconfig exit code
From: Sam Ravnborg <sam@ravnborg.org>
If the user decides to not write the config file out, menuconfig exits with

<akpm@osdl.org>
[PATCH] fix up CPU detection in p4-clockmod
From: Dominik Brodowski <linux@dominikbrodowski.de>
Too many users use the p4-clockmod cpufreq driver instead of the more
advanced speedstep-centrino, speedstep-ich or even acpi drivers. All of
the latter (usually) provide voltage scaling, while the p4-clockmod driver
only offers a variant of frequency scaling. So, warn users if they try out
this driver instead.
Also, instead of using a local copy, use the speedstep_lib infrastructure
for detecting the processor speed. Adding the Pentium-M get_frequency
function to that module only costs about 200 bytes in object size.

[PATCH] suspend/resume support for PIT

This adds proper suspend/resume support for PIT. That means that clock are

<akpm@osdl.org>
[PATCH] Alpha: make prefetch_spinlock() a no-op on UP
From: Ivan Kokshaysky <ink@jurassic.park.msu.ru>
When CONFIG_SMP is not set, spinlock_t is an empty structure, so its
address has arbitrary alignment.
The prefetch instructions with unaligned address don't have visible side
effects on alphas with SRM console (except performance degradation) - the
PALcode handles unaligned traps caused by prefetch instructions internally.
However, on old AlphaBIOS/MILO boxes unaligned prefetch leads to unhandled
alignment trap and kernel panic.
<akpm@osdl.org>
[PATCH] Fix statically declare FIXMAPs
From: Anton Blanchard <anton@samba.org>, me.
Two uses of the FIXADDR_USER_START/END things are problematic:
a) ppc64 wants the FIXADDR area to be at a different location on 32bit and
64bit tasks. On 32bit we want it just below 4GB but that gets in the way
on 64bit. By putting both right at -(some small amount) we can also use
some ppc tricks to get there real quickly (single instruction branches).
b) We assume that FIXADDR_USER_START and FIXADDR_USER_END are constants.
This breaks the UML build.
Fixes:
- Call it all gate. We currently have half the stuff called fixmap and
the other gate, lets be consistent.
- Create in_gate_area(), get_gate_vma() and use it in both places
- Provide defaults for in_gate_area/get_gate_vma, allowing an arch to
override it. (I used CONFIG_* but am open to better suggestions here)
- The /proc/pid/maps vma wasnt marked readable but the get_user
vma was. That sounds suspicious to me, they are now both the same VMA
and so have the same (read,exec) permissions

[PATCH] tmpfs readdir does not update dir atime
From: mark@borgerding.net
Access times of tmpfs dirs do not get updated on readdir. This can cause
empty dirs to get tmpwatch'd too early, b/c atime never changes even though
the dir is in use.

[PATCH] Add bdev private field
From: Christoph Hellwig <hch@lst.de>
Currently xfs has a per-bdev (and XFS filesystem uses up to three underlying
block devices) object that Al complained about loudly that it should be gone.
But for that to happen without rewriting half of XFS (and changing layering
in a way that we don't really want) we need an additional fs-private variable
in struct block_device.

[PATCH] ext3: fix determination of inode journalling mode

[PATCH] Arrange for EFI-related code to be compiled away
From: David Mosberger <davidm@napali.hpl.hp.com>
There is some EFI-related code which is present in the ia64 build but is not
needed: variable efi_enabled is always zero.
The patch fiddles with the efi_enabled definition to arrange for
`efi_enabled' to be constant zero or constant one in those situations where
this can be guaranteed.

[PATCH] make gcc 3.4 compilation work
From: David Mosberger <davidm@napali.hpl.hp.com>

Otherwise these sections get dropped from the final image (I assume).

Julie DeWandel noticed that in the error case where elf_map has failed,

[PATCH] ppc cond_syscall fix
From: Matt Mackall <mpm@selenic.com>
Experimenting with trying to use cond_syscall for a few arch-specific
syscalls, I discovered that it can't actually be used outside the file
in which sys_ni_syscall is declared because the assembler doesn't feel
obliged to output the symbol in that case:
weak.c:
#define cond_syscall(x) asm(".weak\t" #x "\n\t.set\t" #x ",sys_ni_syscall");
cond_syscall(sys_foo);
$ nm weak.o
U sys_ni_syscall
One arch (PPC) is apparently trying to use cond_syscall this way
anyway, though it's probably never been actually tested as the above
test was done on a PPC.
After trying a bunch of tricks to get it to work nicely, I decided
there are basically two alternatives: make weak versions of
sys_ni_syscall wherever they're wanted or put the arch-specific
cond_syscalls in kernel/sys.c where sys_ni_syscall is defined.
The former approach is a bit crufty and doesn't actually do the right
thing in practice as you'll get multiple copies of sys_ni_syscall in
your final image.
The latter introduces some slight arch-pollution in sys.c, but as
arch-specific cond_syscalls aren't all that frequent, it should be
pretty minor. So here's a patch to move the current offender to sys.c:

<B.Zolnierkiewicz@elka.pw.edu.pl>
[PATCH] pdc202xx_old.c: sanitize 66MHz clock use
Sanitize 66MHz clock use: "enable" 66MHz clock before starting UDMA3/4/5
read/write transfer and "disable" it after finishing transfer.
- fixes timings for non-UDMA3/4/5 operations (correct 33MHz timings are used)
- allows using UDMA3/4/5 modes on a capable drive even if non-UDMA3/4/5 drive
is present on the same channel
- fixes corner case when one drive on the channel was using UDMA66/100 + LBA48
(so clock was enabled/disabled for each read/write) and other one was using
UDMA66/100 + LBA28, it could happen that request on LBA48 drive disabled
66MHz clock and it was not enabled for the next transfer on LBA28 drive

is sorted reasonably early - just after kmem_cache_init - but that
could be moved even earlier if necessary.
There is now a lib/extable.c which includes the sort_extable()
function from arch/ppc/mm/extable.c and the search_extable() function
from arch/i386/mm/extable.c, which had been copied to many
architectures. On many architectures, arch/$(ARCH)/mm/extable.c
became empty and so I have removed it.
There are four architectures which do things differently from i386:
alpha, ia64, sparc and sparc64. Alpha and ia64 store the offset from
the offset from the exception table entry to the instruction, and
sparc and sparc64 have range entries in the table. For those
architectures I have added empty sort_extable functions. The
maintainers for those architectures can implement something better if
they care to. As it is they are no worse off than before.
Although it is a moderately sizable patch, it ends up with a net
reduction of 377 lines in the size of the kernel source. :)
I have tested this on x86 and ppc with a module that uses __get_user
in an init function, deliberately laid out to get the exception table
out of order, and it works (whereas it oopsed without this patch).

Make sure we don't access "cmd" in ide-scsi after having
started the command - it may not exist any more.
In particular, load the host early in order to do proper
locking without having to access the command structure later.

[ARM PATCH] 1711/1: pxa2xx_udc (3/5) add udc platform_device, platform_data

This declares the pxa2xx_udc platform device, defines

[ARM PATCH] 1741/1: Add ARM710T processor functions
Patch from Tony Lindgren
Following patch adds ARM710T processor support to proc-arm720.S.

mailing list in December, with a link to the thread here:
http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2003-October/017596.html
NEC ARM710T is used in Psion Windermere architecture, and possibly
other systems.
710T works fine with the 720T functions, except the high_mapping
does not work for vectors_base(). Even if the high bit register is
set, the vectors stay at 0x00000000 instead of 0xffff0000.

[PATCH] USB UHCI: fix broken data toggles for queued control URBs
This patch fixes a long-standing (albeit unidentified) problem in the
queueing code for the UHCI HCD. The code propagates data toggle settings
between messages in a queue for control transfers just the same as bulk
and interrupt transfers. That is a mistake, since control messages always
restart with data toggle 0. With this patch, the UHCI driver now passes
test 10 (control URB queueing) in David Brownell's usbtest suite.
The patch appears to change more than it really does, because it alters
the indentation level of a large section of code.

[PATCH] USB: hiddev HIDIOCGREPORT not blocking in 2.6
I've noticed in 2.6 kernels that HIDIOCGREPORT does not wait for io
completion before returning to the caller. This creates a few unpleasant
issues for userspace:
First, code sequences such as...
ioctl(fd, HIDIOCGREPORT, &rinfo);
ioctl(fd, HIDIOCGUSAGE, &uinfo);
ioctl(fd, HIDIOCGSTRING, &sdesc);
...that used to work in 2.4 now fail in 2.6 if the device takes more
than a few milliseconds to respond to HIDIOCGREPORT. (I'm seeing this
issue on APC UPSes, FWIW.)
Second, userspace code can easily flood the kernel with control messages
since the kernel provides no "backpressure". The result is a lot of
"hid-core.c: control queue full" errors and lost reports.
2.6 hid-core.c appears to submit the request and return immediately.
Although the 2.4 code differs significantly, I traced the call path to
usb-core.c, which seems to block with a timeout, so the code supports my
userspace observation. (Assuming I didn't misread it.)

[PATCH] USB Storage: Notify the SCSI layer about device resets
According to James Bottomley, we need to notify the SCSI midlayer whenever
we issue a driver-initiated device reset. That can happen in several
places, most notably following a transport error. This patch adds
code to the reset routine to take care of it. (Notifying about resets
requested by the midlayer itself is unnecessary but harmless.)

[PATCH] Fix for 32-bit execve() error path
From: David Gibson <david@gibson.dropbear.id.au>
The patch below fixes a bug in ppc64's 32-bit execve() path. It duplicates
logic already in the normal fs/exec.c do_execve() to avoid dropping a NULL
mm. The bprm.mm becomes NULL once the exec passes the "point of no
return". Without this patch a failure past that point (e.g. mmap()
failure) will cause an oops, with it just a killed process.

[PATCH] One-shot support for epoll
From: Davide Libenzi <davidel@xmailserver.org>
The attached patch implements the one-shot support for epoll. Because of
the way epoll works (hooking f_op->poll()) the ET behavior is not really ET
because it might happen that, while data is still available to read (for
the EPOLLIN case), another chunk will become available triggering another
event.
While those conditions can be easily be handled in userspace, the absolute
triviality of the patch and the avoidance of user/kernel space switches and
f_op->poll() calls, make IMHO worth doing this inside epoll itself.

[PATCH] md: fix return code in set_disk_faulty()
From: NeilBrown <neilb@cse.unsw.edu.au>
Following are 10 patches for md in 2.6.1-lastest.
1-6 are simple bugfixes that I am confident should be in 2.6.2.
7 is a bugfix that is fairly important, but could probably do with a
bit more testing first. It is not impossible that it could deadlock,
though I think I have caught and fixed all the problems.
8-10 are code simplication.
So maybe 7-10 should only go in -mm for now, but if it is a while
before 2.6.2, then maybe they can go in a 2.6.2-pre.

[PATCH] md: Don't allow raid5 rebuild to swamp raid5 stripe cache
From: NeilBrown <neilb@cse.unsw.edu.au>
raid5 rebuild takes stripes so agressively that other access cannot get a

stripes to let other processes have a chance.
akpm: I was worried about starvation due to the harsh semantics of yield() in
2.6. But Neil has performed specific testing for that and things seem OK.
If people do note CPU starvation problems we will need to replace the yield()
with a schedule_timeout(1).

[PATCH] md: Small fixes for timely writing of md superblocks.
From: NeilBrown <neilb@cse.unsw.edu.au>
Currently a raid0 superblock is only written when the array is stopped, so a
crash between creation and stop can lose your data.
This patch marks a superblock 'dirty' at creation and forces a dirty
superblock to be written when the array is started.
Previously we would prod the per-array thread at this point, but as it avoids
certain chores when the array is locked, and the array is locked at this
point, that isn't guaranteed to do the right thing. Instead we prod the
thread whenever the array is unlocked.
Finally, only write the superblock at array stop if it is needed to mark the
array as 'clean'. raid0 which is never dirty, doesn't need this.

Russell was unable to correctly migrate this driver to the new

TIOCMBIS/TIOCMBIC do not control only the DTR signal, but also the RTS,
OUT1 and OUT2 signals, or even maybe nothing at all. Plus, these IOCTLs
are no longer passed down to the driver. Instead, drivers should
implement tiocmget and tiocmset driver methods.
so mark it as broken so as to not break allmodconfig/allyesconfig.

Here is a patch for the 2.6.1 kernel that fixes an oops that occurs when
the sunrpc module is unloaded.
The problem was the RPC cache_register() call was not saving entry pointers
to the procfs entries it was creating. So when it came time to dismantle
the entires, a BUG_ON() was tripped in remove_proc_entry() since the tree
was not broken down completely.

[PATCH] afs: avoid ifdef inside macro expansion
From: David Howells <dhowells@redhat.com>
Eliminate the printing of the cache token if present: using cpp
conditionals inside macro expansions is not legal and some gcc's fail it.

[PATCH] do not use shared extable code for ia64
From: Jes Sorensen <jes@trained-monkey.org>
The new sort_extable and shared search_extable code doesn't work on ia64.
I have introduced two new #defines that archs can define to avoid the
common code being built. ARCH_HAS_SEARCH_EXTABLE and
ARCH_HAS_SORT_EXTABLE.
