Summary of changes from v2.6.12-rc1 to v2.6.12-rc2
==================================================
<scjody@modernduck.com>
Description: Use wait_event_interruptible() instead of the deprecated
interruptible_sleep_on(). The first change is simply to clean up the code a
little to make it clearer. The second actually does a replacement, mimicking
exactly the first. I removed the #if 1/#else/endif logic, as it duplicated
the
same code. Patch is compile-tested.

[ACPI] Add ACPI-based memory hot plug driver.
The ACPI based memory hot plug driver patch supports physical hotplug
operations on memory. This driver fields notifications for memory add
and remove operations from firmware and notifies the VM of the affected
memory ranges. Accordingly, this driver also maintains and updates the
states of all the memory ranges. This driver is useful on hardware which
helps firmware generating ACPI events for every physical hotplug
operation of memory boards on the system during runtime.

[IA64] fix IOSAPIC destinations when CONFIG_SMP=n
Always use cpu_physical_id() (which is really the ID/EID of
a processor's Local SAPIC) when programming IOSAPIC entries.
Previously we sometimes used hard_smp_processor_id(), which
is correct when CONFIG_SMP=y but wrong otherwise.

ohci1394.c allocates the legacy IR DMA Context on demand. This happens in IRQ
path resulting in call to dma_pool_create from within interrupt. Same is true
for de-allocation of the IR DMA Context - it happens again in IRQ path
resulting in call to dma_pool_destroy.
After attempting to fix the above by using schedule_work for delayed
allocation and de-allocation, it was determined that it should be fixed
simply by moving the allocation to the drivers probe() function and
de-allocation to remove() function. This way it reduces the complexity and
does not result into any significant wastage of resources.
This patch also fixes duplicate pci pool names and removes spaces from the
names to make it easier for parsing by scripts.
Thanks go to Dave Brownell for greatly simplifying this.

[ACPI] fix kobject_hotplug() use by ACPI processor and container drivers
A while ago, the drivers used their own function
'processor_run_sbin_hotplug() and container_run_sbin_hotplug()' to notify
the agent script using /sbin/hotplug mechanism. But, they were changed to
use kobject_hotplug() instead and this has caused a side effect.
The container driver was supposed to invoke a container.agent (user mode
agent script) using /sbin/hotplug mechanism, but after the changes, it is
not able to call the agent any more and kobject_hotplug() in the
container.c became to invoke a namespace.agent instead if exists. So, I
would like to use the namespace.agent to handle container hotplug event (or
something else) and let the agent to call proper agent (e.g.
container.agent). But, there is an issue we need to solve. When the
namespace.agent is called, a path name of associated kobject is passed as a
DEVPATH (e.g./sys/firmware/ acpi/namespace/ACPI/_SB/DEV0). However, the
agent would not know what device is associated with the DEVPATH nor which
agents to call since the DEVPATH name depends on platform. The attached
patch is to add .hotplug_ops member to acpi_namespace_kset structure and
let it to set a driver name attached to the target kobject into the envp[]
variable as a DRV_NAME element. With this, the namespace.agent can call
proper agents (e.g. container.agent) by refering the DRV_NAME.

[ACPI] fix ACPI container driver's notify handler.
Previously, the handler tried to make a container device be offline if an
ACPI_NOTIFY_BUS/DEVICE_CHECK notification is performed on the device was
present and has its acpi_device. But, the condition is weird. Whenever
the notification is performed, there should be only the following two
conditions:
1. the device is present, but does not have its acpi_device.
2. the device is not present, but has its acpi_device.
#1 is a hot-addition case, which was handled properly also in previous
handler. #2 is a surprising hot-removal case, which was not handled in
previous handler.

[ACPI] fix sysfs "eject" file
This fixes a if-statement in setup_sys_fs_device_files(). It seems to
assume that 'struct acpi_device_flags.ejectable' indicates whether a device
has _EJ0 or not. But this is not a right assumption. It indicates whether
a device has _EJ0|_EJD (See acpi_bus_get_flags() function).
setup_sys_fs_device_files() creates 'eject' file for devices that have _EJ0
control method under a corresponding directory in
/sys/firmware/acpi/namespace/ACPI/. 'eject' file is used to trigger
hot-removal function from userland.

[IA64] fix bad emulation of unaligned semaphore opcodes
The method used to categorize the load/store instructions in
arch/ia64/kernel/unaligned.c is masking the entire set of instructions
described in Table 4-33 of the 2002 Intel Itanium Volume 3: Instruction
Set Reference.
It's the set of instructions for opcode 4, mbit 0, x bit 1, described
as Semaphore/Get FR/16-Byte Opcode Instructions.
Because the IA64_OPCODE_SHIFT and IA64_OPCODE_MASK operations ignore
the x bit, this set of instructions (including cmpxchg, xchg, and
fetchadd among others) are processed like the corresponding opcode 4,
mbit 0, x bit 0 instructions.
This means that a cmpxchg.acq with a misaligned pointer will return the
old value without setting the new one (rendering spin locks as No-ops)
and that the other instructions also appear not to update memory.
A cmpxchg.rel will be treated like a ld.s and just retry forever.
The correct behavior for this class of instructions is documented
in the file as producing failures for user code and kernel oops in
kernel mode, but the code as implemented does not behave this way.
I have user test code to demonstrate the problem if you would like
a copy.
The simple fix in this patch has been discussed with Stephane Eranian
and David Mosberger. It has the advantage of not requiring the
redesign of the opcode discrimination in unaligned.c.

[ACPI] ACPICA 20050309 from Bob Moore
The string-to-buffer implicit conversion code has been
modified again after a change to the ACPI specification.
In order to match the behavior of the other major ACPI
implementation, the target buffer is no longer truncated
if the source string is smaller than an existing target
buffer. This change requires an update to the ACPI spec,
and should eliminate the recent AE_AML_BUFFER_LIMIT issues.
The "implicit return" support was rewritten to a new
algorithm that solves the general case. Rather than
attempt to determine when a method is about to exit,
the result of every ASL operator is saved momentarily
until the very next ASL operator is executed. Therefore,
no matter how the method exits, there will always be a
saved implicit return value. This feature is only enabled
with the acpi_gbl_enable_interpreter_slack flag which
Linux enables unless "acpi=strict". This should
eliminate AE_AML_NO_RETURN_VALUE errors.
Implemented implicit conversion support for the predicate
(operand) of the If, Else, and While operators. String and
Buffer arguments are automatically converted to Integers.
Changed the string-to-integer conversion behavior to match
the new ACPI errata: "If no integer object exists, a new
integer is created. The ASCII string is interpreted as a
hexadecimal constant. Each string character is interpreted
as a hexadecimal value ('0'-'9', 'A'-'F', 'a', 'f'),
starting with the first character as the most significant
digit, and ending with the first non-hexadecimal character
or end-of-string." This means that the first non-hex
character terminates the conversion and this is the code
that was changed.
Fixed a problem where the ObjectType operator would fail
(fault) when used on an Index of a Package which pointed
to a null package element. The operator now properly
returns zero (Uninitialized) in this case.
Fixed a problem where the While operator used excessive
memory by not properly popping the result stack during
execution. There was no memory leak after execution,
however. (Code provided by Valery Podrezov.)
Fixed a problem where references to control methods within
Package objects caused the method to be invoked, instead
of producing a reference object pointing to the method.
Restructured and simplified the pswalk.c module
(acpi_ps_delete_parse_tree) to improve performance and reduce
code size. (Code provided by Alexey Starikovskiy.)

JFS: Don't clobber wait_queue_head while there are waitors on it
The resize code closes down the log and reinitializes it in another location
on the disk. The problem is that it re-initializes a wait_queue_head while
there are waitors waiting for the resize to be completed. The result
is that the waitors are never awakened.

[ARCH]: Consolidate portable unaligned.h implementations.
Several architectures do their asm/unaligned.h support support by
simply casting the pointer to a packed strcuture, then deref'ing that
pointer. This forces gcc to assume the object is not aligned
properly.
This technique originated in Richard Henderson's
asm-alpha/unaligned.h, IA64 uses the same technique as well.
This works well on RISC systems for two reasons:
1) On systems like Alpha, MIPS, et al. which have special
"load unaligned" instructions, GCC knows to emit them
for code like this.
2) Even on systems without explicit unaligned load/store instruction
support, the code emitted (basically, byte loads with shifts and
ors) is about the same as what you get when emitting a memmove()
call and you don't need the local stack slot.
I was going to thus move asm-sparc64/unaligned.h over to such a
scheme, but then I noticed that nobody actually includes the current
memmove() based asm-generic/unaligned.h code. So why not put the
portable packed structure implementation into asm-generic/unaligned.h
and then make asm-{alpha,ia64,sparc64}/unaligned.h simply include that?
I only had to make minor modifications to the alpha header when placing
it into the generic area. In particular I had to convert some explicit
"unsigned long", "unsigned int" et al. into the arch-agnostic "u64" "u32"
etc. so that even 32-bit platforms could use this.
Come to think of it I'll make sparc32 use this as well.
I looked at all the other platform unaligned.h headers:
I386/X86_64: can do unaligned loads directly
ARM: is trying to be incredibly clever, and open codes the shifts and
ors. I think it would be better if it used something similar to
the packed structure technique.
CRIS: like x86, can do unaligned stuff directly.
FRV: needs help doing unaligned stuff, it probably also could use the
packed structure stuff.
H8300: needs help, could use this new asm-generic/unaligned.h header
M32R: likewise
M68K: can do unaligned access directly.
MIPS: appears to be a copy of the original alpha/ia64 unaligned.h
header, so I converted it to use the new asm-generic/unaligned.h
too
PARISC: is just a copy of asm-sparc/unaligned.h, so I converted it
over to use asm-generic/unaligned.h too
PPC/PPC64: can do unaligned access directly in big-endian mode which
is what the Linux kernel runs in
S390: can do it directly as well
SH/SH64: just has the memmove() code ala asm-sparc/unaligned.h, I
converted it to use asm-generic/unaligned.h
V850: has some clever code just like ARM, so I didn't touch it.
So this is the patch I came up with.

[PATCH] USB: ehci and short in-bulk transfers with 20KB+ urbs
This changes handling of short bulk IN transfers with URB buffers that

two or more transfer descriptors. The case is rare in most systems, since
few

The existing code misbehave on at least NEC's EHCI 0.95 silicon, where it
seems
to hit a new variant of a silicon quirk relating to dummy TDs. Symptom of
the
misbehavior is that the host stops polling on the IN endpoint, and the URB
queue
no longer progresses.

[PATCH] USB: ethernet/rndis gadget driver updates
Various fixes to the Ethernet/RNDIS gadget core code:
- Pre-allocate the request used to transfer status back to the host.
Used initially for CDC Ethernet; RNDIS will change later. This
resolves a longstanding FIXME, elimininating fault modes.
- Use larger packets for those status reports, 16 bytes not 8; this
eliminates some fault modes, without losing hardware support.
- Streamline endpoint configuration, just save the endpoints during
driver binding. The previous scheme was a complex leftover from
before the endpoint autoselection library code existed, and this
bit of cleanup prepares for more simplifications later.
- Implement a basic outgoing packet filter, for CDC Ethernet and RNDIS
but not the CDC subset. This improves conformance to both specs.
- Correct the bit rate reports for CDC Ethernet and RNDIS to match
the peak bulk transfer rates, not the raw signaling rates.
This still doesn't issue CDC or RNDIS link status change notifications
to the host as often as it should, but that'll be easier now.

[PATCH] USB Storage: Header reorganization
This patch started life as as471 from Alan Stern, and has been regenerated
against the current tip.
This patch cleans up the use of header files. Primarily it makes sure
that "usb.h" is included before any of the other local headers. It also
removes some unnecessary declarations of struct us_data and struct
scsi_cmnd, and it moves the inclusion of <scsi/scsi_host> to usb.h where
it will be needed by a later patch.

[PATCH] USB Storage: change how unusual_devs.h flags are defined
This patch started life as as473 from Alan Stern, and has been rediffed
against the current tip.
This patch changes the way the flags bits are defined, so that the
proc_info routine can automatically list all the flags that are set. As a
side effect it will also include the NEED_OVERRIDE flag; that shouldn't
really matter. (As another side effect, the definitions grew too long to
fit on a single 80-character line so I had to wrap the comments.)
This patch also takes the opportunity to remove a couple of obsolete flags
and to renumber the bit values. The patch also removes an unusual_devs
entry whose only purpose was to set one of those obsolete flags; apparently
it got left behind when all the other uses of those flags were removed.

Somehow I missed four files with dst_pmtu usages in them. I'm going

Here is a patch that replaces dst_pmtu with dst_pmtu in ipmr.c

in ipip.c.
As it is we may send ICMP packets when IPsec is present which is
exactly what the comment says that we shouldn't do.

This patch makes ipt_TCPMSS use the correct MTU value for clamping.
This is a bit tricky actually since TCPMSS can be used in FORWARD,
LOCAL_OUT as well as POST_ROUTING.
In the first two cases we haven't performed IPsec yet so dst_mtu
obviously does the right thing. As it is, POST_ROUTING is performed
after xfrm_output so MSS clamping is useless there.
With Patrick's IPsec netfilter stuff, there will be a POST_ROUTING
processing before IPsec processing, in which case dst_mtu also returns
exactly what we want.

[IPV4]: Kill remaining unnecessary uses of dst_pmtu
Once again here is a couple of trivial dst_pmtu/dst_mtu replacements.
In both locations, we can only have simple dst entries which means
that dst == dst->path.
BTW, this is the rule that we should apply in future for uses of
dst_mtu/dst_pmtu (or other metrics on dst). If the only dst's that
can appear are simple dst's (dst == dst->path), then we should use
dst_mtu or dst_metric. If dst != dst->path, then whoever is writing
the code will need to think about which of dst or dst->path is the
right one.
In most instances dst will be the one. However, as we have seen in
ip_append_data, dst->path may be needed rarely. In particular, if
we're doing fragmentation immediately after IPsec, then you may need
it.

This patch makes xfrm4_encap/xfrm6_encap use dst->child instead of

[PATCH] ppc32: Clean up mv64x60 bootwrapper support
This patch removes the call to mv64x60_init() in
arch/ppc/boot/simple/head.S and now uses the 'load_kernel()' hook to call
to have mv64x60-specific code called. This means that the mv64x60 code
will be called after the bootwrapper has relocated itself. The platforms
affected by this change are updated by this patch as well.

[PATCH] ppc64: fix kprobes calling smp_processor_id when preemptible
When booting with kprobes and preemption both enabled and
CONFIG_DEBUG_PREEMPT=y, I get lots of warnings about smp_processor_id being
called in preemptible code, from kprobe_exceptions_notify. On ppc64,
interrupts and preemption are not disabled in the handlers for most
synchronous exceptions such as breakpoints and page faults (interrupts are
disabled in the very early exception entry code but are reenabled before
calling the C handler).
This patch adds a preempt_disable/enable pair to kprobe_exceptions_notify,
and moves the preempt_disable() in kprobe_handler() to be done only in the
case where we are about to single-step an instruction. This eliminates the
bug warnings.
From: Ananth N Mavinakayanahalli <ananth@in.ibm.com>
The patch is fine, but it seems to break jprobes - we have an unbalanced
preempt_enable/disable path while handling jprobes. Patch below is

[PATCH] ppc64: make cpu hotplug play well with maxcpus and smt-enabled
This patch allows you to boot a pSeries system with maxcpus=x or
smt-enabled=off (or both) and bring up the offline cpus later from userspace,
assuming the kernel was built with CONFIG_HOTPLUG_CPU=y.
- Record cpus which were started from OF in a cpu map and use that instead
of system_state to decide how to start a cpu in smp_startup_cpu.
- Change the smp bootup logic slightly so that the path for bringing up
secondary threads is exactly the same as hotplugging a cpu later from
userspace.
- Add a new function to smp_ops - cpu_bootable. This is implemented only by
pSeries to filter out secondary threads during boot with smt-enabled=off.
Another way this could be done is to change the kick_cpu member to return
int and we can check for this case in smp_pSeries_kick_cpu.
- Remove the games we play with cpu_present_map and the
hard_smp_processor_id to handle smt-enabled=off, since they're now
unnecessary.
- Remove find_physical_cpu_to_start; assigning threads to logical slots
should be done at bootup and at DLPAR time, not during a cpu online
operation.
One caveat: you need up-to-date firmware on Power5 for the maxcpus option to
work on systems with more than one processor. Otherwise interrupts get
misrouted, typically resulting in hangs or "unable to find root filesystem"
problems.
Tested on Power5 with and without CONFIG_HOTPLUG_CPU and with various
combinations of the maxcpus= and smt-enabled= parameters.

do_signal_stop race case misses unlock, and fixing it fixes the symptom.

[PATCH] Possible VIA-Rhine free irq issue
It seems to me that in the VIA Rhine device driver the requested irq might

There is a problem with the way sdev is freed currently. The reason is
really that there is a circular referencing problem: the sdev needs to
hold on to the queue, but the queue (through the request function) also
needs to hold on to the sdev.
The easiest way to work-around this problem is to kill the sdev
reference in the queue when the sdev is freed. On invocation of
scsi_request_fn(), kill io to this device.

Although everything is fine. The initial "target did not report SYNC"
is because the driver is trying to negotiate over the initial inquiry
(so, naturally we don't know if it supports sync yet). The solution is
to rip out the last remnants of the spontaneous attempts at negotiation
to force it to wait for the DV negotiation in slave_configure.

[ARM PATCH] 2571/1: minor time-keeping fixes for ixp2000
Patch from Lennert Buytenhek
There are two very minor issues with time-keeping on the ixp2000:
1. It turns out that if T#_CLD (timer reload value) is set to X,
it means the timer will spend a full tick on 0, then a full
tick on X, and then start counting down towards 0, which then
effectively gives the timer a period of X+1 instead of the
intended X. Solve by writing X-1 instead of X to T#_CLD.
This is relatively harmless, though -- assuming a 50MHz system
clock (like on the ENP-2611) and HZ=100, there will be 500000
timer interrupts generated per 500001 real-world jiffies, but
that last timer interrupt will call timer_tick twice, taking the
system time from 499999 jiffies plus 20000 usec to 500001 jiffies
plus 0 usec. Every 500000th jiffy will 'not exist', and every
other jiffy will last 10002us instead of 10000us.
2. next_jiffy_time is initialised as '0xffffffff - ticks_per_jiffy',
but timer 4 starts ticking from 0xffffffff downwards, which will
cause the time offset in the first 1/HZ sec after timer int init
to be negative, and the first timer interrupt ever not to call
timer_tick().
Neither of these issues can cause clock drift or backwards clock
motion, but it's good to fix them nevertheless.

[ARM PATCH] 2573/1: simplify align[bw]() in ixp2000's io.h and update
comments
Patch from Lennert Buytenhek
We currently have a workaround for the fact that early IXP2400s
assert byte lanes for PCI I/O transactions the other way round.
Newer silicon has a bit that can be set to 1 to get the 'proper'
behavior, but since that is not available on older silicon we
choose to keep working around this issue by hand.
The workaround can be done in an easier way than is currently the
case, though -- instead of substracting the lower two bits of the
I/O address from 3 and putting the result back into the lower two
bits, we can just toggle the two lowest bits using a simple XOR
with 3.
While we are at it, the outb() macro does not seem to parenthesize
its first argument, while outw() and outl() do, so fix this up.

[ALSA] fix P16V breakage for non Audigy2 cards
EMU10K1/EMU10K2 driver

handler resulting in infinite loop and system lockup on any non Audigy2
cards. I really hate checking emu->is_audigy and emu->revision in a
fast path like the IRQ handler but I don't see another way.
Also, don't bother allocating/freeing the DMA buffer for P16V unless
it's really present.
This is a critical fix and should trigger an immediate rc2 release IMO.
Currently any emu10k1 users other than Audigy 2 will lock up hard as

[ARM PATCH] 2575/1: pass -mbig-endian/-mlittle-endian to invocations of cpp
Patch from Lennert Buytenhek
We currently pass -mbig-endian/-mlittle-endian to the compiler and the
assembler, but we do not pass it to cpp, even though it also needs it.
So, add this flag to CPPFLAGS, and since CPPFLAGS is also passed to the
compiler and the assembler, we can then then remove the flag from CFLAGS
and AFLAGS.
The symptom of this problem is the kernel hanging after
"Memory: ......KB available (....K code, ...K data, ...K init)"
when compiling a big-endian kernel with a little-endian toolchain or
vice versa, and this happens because 'jiffies' points to the wrong
half of 'jiffies_64' (due to vmlinux.lds having been generated with
the wrong preprocessor flags), so calibrate_delay() takes forever to
complete.

[PATCH] b44: allocate tx bounce bufs as needed
From: "John W. Linville" <linville@tuxdriver.com>
The b44 hardware has a DMA mask that only covers 1GB. On x86, a DMA mask
<4GB results in allocations using GFP_DMA. The GFP_DMA pool (16MB) gets
exhausted very quickly in some configurations.
The b44 driver has been pre-allocating bounce buffers in a single large
(~750k) contiguous block. On boxes w/ limited GFP_DMA memory, this
allocation can fail. Such failure results in the driver being unable to
load and function.
The solution here is to check each tx skb against the DMA mask. If it is
outside the allowable range, a single buffer is allocated from the GFP_DMA
range and discarded after the tx completes. This behaviour mimics what is
done for bounce buffers on the rx side.
The pre-allocation of tx bounce buffers is, of course, removed.

Make Fusion-MPT much faster as module
From: Moore, Eric Dean <Eric.Moore@lsil.com>
Between the 3.01.16 and 3.01.18, we introduced new method
to passing command line options to the driver. Some of the
command line options are used for fine tuning dv(domain
validation) in the driver. By accident, these command line options were
wrapped around #ifdef MODULE in the 3.01.18 version of the driver.
What this meant is when the driver is compiled built-in the kernel,
the optimal settings for dv were ignored, thus poor performance.
There was actually a fix for this when I submitted SAS drivers
to the mailing list back in November, however the SAS drivers was
rejected, and later on I overlooked submitting a single patch to
solve this.

[CRYPTO]: Do scatterwalk_whichbuf inline.
scatterwalk_whichbuf is called once for each block which could be as
small as 8/16 bytes. So it makes sense to do that work inline.
It's also a bit inflexible since we may want to use the temporary buffer
even if the block doesn't cross page boundaries. In particular, we want
to do that when the source and destination are the same.
So let's replace it with scatterwalk_across_pages.
I've also simplified the check in scatterwalk_across_pages. It is
sufficient to only check len_this_page.

[CRYPTO]: Split src/dst handling out from crypt()

This sets the stage for further optimisations down the track without
polluting crypt() itself.
These helpers don't belong in scatterwalk.[ch] since they only help
the particular way that crypt() is walking the scatter lists.

We have long since stopped using a null cit_iv as a means of doing null
encryption. In fact it doesn't work here anyway since we need to copy
src into dst to achieve null encryption.

[IPV4]: Check mtu instead of frag_list in ip_push_pending_frames()
I still didn't like the fact that ip_append_data was the only user
of dst_pmtu :) So I went looking for bugs in the surrounding code.
I managed to find something in ip_push_pending_frames.
When dst_mtu < dst_pmtu - IPsec overhead (which can be caused by PMTU
discovery within an IPsec tunnel), and we transmit a packet that's
longer than dst_mtu but shorter than dst_pmtu - IPsec overhead, then
the DF bit will be incorrectly set in the inner IP header.
This will cause the packet to be dropped when it hits the router that
generated the original PMTU event. Unfortunately the ICMP packet coming
back doesn't tell us anything new so the next time we send a packet we
will do exactly the same thing.
The fix is similar to what we did in ip_output. Instead of checking
whether frag_list is empty, we check the condition skb->len <= dst_mtu
directly and set the DF bit based on that.
We can enumerate all the possibilities to see that this is correct.
If skb->len <= dst_mtu and frag_list is empty then this does the
samething as before and is obviously correct.
If skb->len <= dst_mtu and frag_list is non-empty then it implies
that dst_pmtu has increased since the fragments were constructed
as dst_pmtu = dst_mtu + IPsec overhead. So the skb will now fit
within a single fragment which means that setting DF is correct.
The fragments will be merged by skb_linearise in dev_queue_xmit.
If skb->len > dst_mtu and frag_list is non-empty then again this
maintains the status quo.
If skb->len > dst_mtu and frag_list is empty then we will leave the
DF bit clear as the packet will need to be fragmented between the
remote IPsec gateway and the final destination.

[IPV4]: Clear DF bit in ip_fragment fast path
It is possible for ip_fragment() to send out head fragments with
both DF and MF set for packets with local_df set to true. This is
because the fast path tries to only modify the MF bit of the head
fragment.
Since the offset is always zero for the head fragment, and we know
that DF should be cleared in case of local_df, we can change |= to
a straight assignment.

[PATCH] USB: ohci-omap update (mostly clock gating)
This syncs the OMAP OHCI code with the latest from the OMAP tree.
The main changes are updated clock gating support (goes with some
clock tree updates, submitted separately) and two minor cleanups:
the platform device resources use physical addressing, not the
static i/o mapped addresses; and there's no longer a need for a
(noexistent in mainstream) separate header file.

[PATCH] USB: pxa25x udc updates, mostly PM
This has various updates to the PXA 21x/25x/26x UDC driver.
- Implement the "new" pullup() and vbus_session() methods, and
use them to keep the UDC 48 MHz clock off much of the time.
* Reworked that ugly Lubbock VBUS IRQ code. Claim both IRQs,
enable only one at a time; clock the UDC only when VBUS is
present. (And get rid of rude runtime messages.)
* Implement driver model suspend() and resume() calls. When
this device suspends, it clocks off the UDC. On boards that
support it (including Zaurus clamshells, but not Lubbock)
the D+ pullup is disabled, so the host won't see the device.
- Hmm, the "latest" errata defined some "Must Be One" bits. OK.
- Change the LED support for debugging. It stopped compiling for
Lubbock a while back. This switches to the standard LED calls
(so it can work on non-Lubbock hardware), removes the EP0 calls
(not very useful any more), and for Lubbock now initializes the
hex leds (U-Boot doesn't enable them, BLOB did).
- "sparse" updates, and get rid of a warning that's pointless
unless someone's working on DMA support;
Tested on Lubbock (VBUS sensing but no pullup) and some Zaurus
clamshells (pullup but no VBUS).

[PATCH] USB Storage: make usb-storage structures refcounted by SCSI
This patch started life as as474 from Alan Stern. It's been rediffed
against the tip, tho that is now several days old.
This patch changes the way our private struct us_data is allocated; now it
gets stored at the end of the Scsi_Host rather than separately. That's
what the hostdata field is intended for, and this is how other low-level
host drivers operate. In order to convert between us_data and the
corresponding Scsi_Host I added two new inline routines: us_to_host and
host_to_us. (The conversion actually should be quicker than before by a
microscopic amount, because now it only involves adding an offset whereas
before it involved dereferencing a pointer.)
The main advantage is that the host is refcounted, so now our us_data
automatically is too. Although that doesn't matter at the moment, it will
matter later on when the control thread may need to outlive the disconnect
callback.

[PATCH] USB Storage: exit control thread immediately upon disconnect
This patch started life as as475 from Alan Stern. It has been rediffed
against the tip, tho that was several days ago.
This patch causes the main control thread to exit as soon as possible,
i.e., as soon as the DISCONNECTING flag is set. It no longer waits for an
explicit exit command, one with srb == NULL.
There won't be any bad implications for our interaction with the SCSI
midlayer, because once the DISCONNECTING flag is set we fail every
submitted command immediately in the queuecommand routine. And if a
command manages to squeeze through the crack (submitted and accepted
before we disconnect but not yet processed), the SCSI midlayer will cancel
it automatically when we remove the host.

[PATCH] USB Storage: allow disconnect to complete faster
This patch started life as as476 from Alan Stern. It has been rediffed
against the tip, tho that was a few days ago.
This patch makes the disconnect() routine not wait for the control and
scanning threads to exit. This may not seem important now, but it will
become important later: We would end up with a deadlock if disconnect()
(which is called with the device locked) was waiting for the control
thread to exit, while the control thread was waiting to lock the device so
it could do an autosuspend.
It's necessary to make sure that the host and us_data structures aren't
deallocated before the control and scanning threads are through with them.
This is done by calling scsi_host_get and scsi_host_put at the start and
end of each thread, before signalling that the threads are running. Since
the probe() and disconnect() routines cannot run concurrently (guaranteed
to us by the USB core), this method will guarantee the structures are not
deallocated too soon.
While there's nothing wrong with leaving the threads alive after
disconnect() returns, there would be a real problem if the threads were
still alive when usb_stor_exit returned! So now usb_stor_exit has to wait
to make sure all the threads have died. Apparently the only safe way for
one thread to signal another while exiting is to use complete_and_exit,
which we've been doing. So the patch adds a new driver-wide struct
completion, named threads_gone, and each thread signals it while exiting.
usb_stor_exit must call wait_for_completion the appropriate number of
times, and that number is stored in a new counter named total_threads.

[PATCH] USB Storage: combine waitqueues
This patch started life as as476, and has been rediffed against the tip.
However, that was a few days ago.
This patch combines the two separate waitqueue heads used by the
scsi-scanning thread and the device-reset routine into one. After all,
until the scanning thread is through waiting there will be no SCSI
devices and hence no device resets.
Once the scanning thread is done waiting, the waitqueue can be used by the
reset logic -- so even if the act of scanning produces resets, we're fine.

- Removes the needless PEGASUS_RUNNING flag, replacing it with the
standard netdevice mechanism.
- Cleaner access for unaligned values. Not all processors spend
silicon to support them like x86 does.
- Adds a few "sparse" fixes.
- Saves the return values for the requests that manipulate chip
registers ... doesn't yet check them, but at least anyone looking
at the code (e.g. to find out why the link check task is wedged...)
will see where those failure modes are ignored. Currently the
errors may be reported by printk, but the netif_msg_*() filters
make that an even worse alert mechanism.

This contains patches to the EHCI driver for the full speed isochronous
transfer support:
- The sitd->hw_buf[1] and sitd->hw_buf_hi[1] fields were not
correctly initialized, affecting transfers which crossed 4K
boundaries. Helps resolve some "buzz" in audio playback.
- Correctly rounds 188-byte OUT transfers to fit into a single
packet ... no split transfers needed. Resolves other "buzz" in
audio OUT streams.
- Fixes a cut'n'paste error in the logic to check for microframe
scheduling collisions with a given transaction translator.
The error caused full speed iso tds to be treated in part as
if they were high speed iso tds, which could oops.
- The split transaction state flag doesn't indicate an error, and
it should be ignored when deciding if (IN) transfers had errors.
- Remove some code rejecting full speed iso IN transfers; it's
not fully working yet though.
Plus a some minor cleanups: reporting the iso start frame in the
relevant units, making a debug message more consistent.

[ARM PATCH] 2507/1: work around ixp2400 erratum #66
Patch from Lennert Buytenhek
Intel's ixp2400 can occasionally corrupt writes to its on-chip
registers, leading to system crashes. The suggested workaround for
this is to map in those registers using XCB=101 instead of XCB=000.
Patch 2491/1 makes all mappings of ixp2000 on-chip I/O regions use
section mappings. This patch makes all iotable section mappings use
XCB=101. This patch depends on 2491/1.
Kernel iotable mappings that are not 1MB-aligned, ioremap(), and
userspace mappings using mmap() on /dev/mem will still generate
XCB=000 mappings, which can trigger erratum #66 quite easily.
For this, an extra patch (to arch/arm/mm/proc-xscale.S) is needed,
which is maintained out-of-tree because it has been rejected in
the past. See http://ixp2xxx.sourceforge.net/kernel/ and look
for 'ixp2000-erratum66-ptes.diff'.
2.6.11-rc4 with 2491/1 plus this patch survives a week of heavy
testing on my ENP-2611, while 2.6.11-rc4 vanilla doesn't stand a

without all the other stuff like proc entries etc. of_add_node and

[PATCH] m68knommu: cleanup ColdFire specific trap handling asm code
A couple of fixes to the ColdFire specific trap handling code:
. do not clear the stack alignment bits in exception frame (in Lreturn)
breaks return stack badly if applications work with stack un-aligned.
. use generated asm-offsets instead of local offset definitions
. use THREAD_SIZE definition instead of hard coding stack size
(this is needed to support 4k stacks)
. some instruction optimization (uses instructions that encode using
ledd bytes)

[SPARC64]: Eliminate g5 register usage from ultra.S
Signed-off-by: David S. Miller <davem@davemloft.net>
<acme@toy.ghostprotocols.net>
[NET] make all protos partially use sk_prot
sk_alloc_slab becomes proto_register, that receives a struct proto not
necessarily
completely filled, but at least with the proto name, owner and obj_size (aka
proto
specific sock size), with this we can remove the struct sock sk_owner and
sk_slab,
using sk->sk_prot->{owner,slab} instead.
This patch also makes sk_set_owner not necessary anymore, as at sk_alloc time
we
have now access to the struct proto onwer and slab members, so we can bump
the
module refcount exactly at sock allocation time.
Another nice "side effect" is that this patch removes the generic sk_cachep
slab
cache, making the only last two protocols that used it use just kmalloc,
informing
a struct proto obj_size equal to sizeof(struct sock).
Ah, almost forgot that with this patch it is very easy to use a slab cache, as it
is
now created at proto_register time, and all protocols need to use
proto_register,
so its just a matter of switching the second parameter of proto_register to '1',
heck,
this can be done even at module load time with some small additional patch.
Another optimization that will be possible in the future is to move the
sk_protocol
and sk_type struct sock members to struct proto, but this has to wait for all
protocols
to move completely to sk_prot.
This changeset also introduces /proc/net/protocols, that lists the registered
protocols
details, some may seem excessive, but I'd like to keep them while working on further
struct sock hierarchy work and also to realize which protocols are old ones, i.e.
that
still use struct proto_ops, etc, yeah, this is a bit of an exaggeration, as all
protos
still use struct proto_ops, but in time the idea is to move all to use sk->sk_prot
and
make the proto_ops infrastructure be shared among all protos, reducing one level
of
indirection.

It is pointless for cases where one tries to boot a kernel

then something a bit more informative than "Error: a" might be

[ARM PATCH] 2576/1: Fix LDRD and LDRSB (Thumb) abort handling
Patch from Deepak Saxena
The ARM LDRD (v5+) and Thumb LDRSB instructions use bit 20/11 (ARM/Thumb)
differently than every other instruction, so it is set to 0 (write) even
though the instructions are read instructions. This means that during an
abort the instructions will be treated as a write and the handler will
raise a signal from unwriteable locations if they fault. We have to
specifically check for these instructions from the abort handlers to
treat them properly. EABI toolchains emit LDRD instructions and even
those not using EABI might have handcoded ASM that uses these instructions.
This patch creates an abort-macro.S file that is included by the
abort-ev* files that need the special cases and changes those
handlers to use the macros. ARMv6 does not need the special case
handling as the HW takes care of setting the FSR bit appropriately.

[ARM] Fix ARM TLB shootdown code
We missed flushing the TLB when we're unmapping only reserved pages.
Since the kernel is now better at passing vmas which correspond
solely with the region to unmap, we can use tlb_*_vma() to do
"just enough" flushing, both for the TLB and cache.
We can avoid all flushes in tlb_*_vma() for the full-MM case, and
just do a flush_tlb_mm(). We can omit the cache flushing because
this thread will die soon.

[SPARC64]: Support >=cheetah+ dual-dtlbs properly.
UltraSPARC-III+ (aka. cheetah+) and later chips have three
D-TLB units. One is fully assosciative and has 16 entries,
the other two have 512 entries each and are 2 way subblocked
and then indexed by the PAGE_MASK bits. This implies that
the two 512 entry TLBs need to know the page size in order
to index things properly.
The page size to use is encoded in page size fields within
the TLB context registers.
Up until this point we just left them at zero, which meant
that both 512 entry TLBs were used for 8K translations only.
The rest (including the 4MB kernel mappings) went into the
16 entry fully assosciative TLB.
Now, for the kernel, we use the first 512 entries for 4MB
mappings and the second 512 entries for PAGE_SIZE mappings
(ie. for vmalloc and modules). For the user, we use the
first 512 entries for PAGE_SIZE and the second 512 entries
for HPAGE_SIZE if the user maps any hugetlb pages else we
use the second half for user PAGE_SIZE stuff as well.
Most of this changeset is clerical. We move most of the
mm->context layout defines into asm/mmu.h, we abstract the
mm->context type so that it is now much easier to see and
trap accesses to the context values. In particular, one
can find all context handling by grepping the sparc64 sources
for CTX_* and {PRIMARY,SECONDAY}_CONTEXT.
Happily, the fast paths of the kernel are mostly untouched
by this new stuff. We add 2 cycles to trap entry, 1 cycle
to trap exit, and 2 cycles to the window trap fixup code.

[PATCH] Add a scsi_device flag for RETRY_HWERROR
It turns out that a bunch of USB-IDE converters make the mistake of
returning SK = 04 (Hardware Error) whenever the IDE device signals any
sort of error, without bothering to distinguish recoverable from
non-recoverable errors. The best way to handle this is for usb-storage to
set a per-device flag indicating that these errors should always be
retried. The current scheme (blacklist flag but no per-device flag) isn't
well suited for this situation.
This patch adds the per-device flag and sets it initially based on the
blacklist setting. Once this has been merged, a separate patch will be
submitted to Matt Dharm adding the corresponding support to usb-storage.

[PATCH] pcmcia: don't send eject request events to userspace
Here follow PCMCIA-related patches which allow for kernel-based matching
between 16-bit PCMCIA devices and their drivers. If you're using this (and
using a special startup script or small tool), you don't need to run
"cardmgr"
any longer. cardmgr still works, though, allowing for a gradual transition.
These patches apply on top of what's in 2.6.11-rc4-mm1; for proper operation
pcmcia-bridge-resource-management-fix.patch should be removed first, though.
Andrew, please apply them to your next -mm release.
1. Theory of operation I: setting up the sockets
================================================
- the appropriate socket driver is initialized (modprobe or built-in)
- a hotplug event (CLASS=pcmcia_socket) is generated
- if it's a socket which doesn't map the resources statically, resources
available for use by PCMCIA cards need to be marked as "allowed". This is
done using either a small shell script[*] or pcmcia-socket-startup[**]. The
latter parses /etc/pcmcia/config.opts -- the same file cardmgr currently
uses for this purpose.
[*] e.g.
#!/bin/sh
echo -n "+ 0x00000100 - 0x000004cf" >
/sys/class/pcmcia_socket/pcmcia_socket1/available_resources_io
echo -n "+ 0x60000000 - 0x60ffffff" >
/sys/class/pcmcia_socket/pcmcia_socket1/available_resources_mem
echo -n "1" >
/sys/class/pcmcia_socket/pcmcia_socket1/available_resources_setup_done
[**] note: for pcmcia-socket-startup to work properly you need a patch for
libsysfs (it is already accepted by the maintainer of the package). See
below for details.
2. Theory of operation II: setting up a device
==============================================
- a pcmcia device is discovered in the socket
- device information is determined and exported to sysfs
- a hotplug event is created, passing -- among others -- a complete MODNAME
string to userspace. Available match flags are the product ID strings [in
userspace, only the hashes are matched -- you can't use strings in
modules.alias], manufactor and card ID, the multifunction device number,
the pseudo-multifunction device number [this is what e.g.
bind "serial_cs", bind "serial_cs"
was before], whether it needs a CIS override, and the function ID [this
match
is only used if it is allowed by userspace -- it should be avoided and will
be removed in future, after existing users have been converted to matches
of
other types].
- modprobe $MODNAME [*]
- the device is matched against drivers. function ID matches are ignored at
this stage. If the device needs a CIS override, it is requested from
userspace using the firmware helpers. It is recommended to have a symlink
either from /lib/firmware/cis/ to /etc/pcmcia/cis/ or the other way to let
both (old) cardmgr and (new) firmware.agent access the override CIS data.
- if no driver was found, an userspace helper checks whether the card is one
of
two(!) which can only be detected using cardmgr's tuple directive. If this
is
the case, a CIS override is done using
/sys/class/pcmcia_socket/pcmcia_socket%n/cis , loading a CIS with proper
identification values.
- if this doesn't lead to a driver being bound to the device, function
ID-based
matches are allowed.
[*] note: for this to work properly you need a patch to be written which
loads
_all_ matching modules, not just one]
3. patches
==========
I'll not send the patches which add the proper device identification tables
to
this list, but only (and a bit later) to Andrew and the appropriate
maintainers. You can find them already at
http://www.kernel.org/pub/linux/kernel/people/brodo/patch...
-- they start with pcmcia-25-
I used all identification information I could find in pcmcia-cs, the kernel,
and some web resources and, but probably missed some. If I did, please send
me either the appropriate device info from the cardmgr config file or the
output of "pcmcia-modalias" (see below) -- or a PCMCIA_MATCH patch.
4. userspace tools
==================
Several GPL[*] userspace tools are required or useful for this (new) method
of
operation. I'll send them to this list for review, and they're also available
_temporarily_ at
http://www.kernel.org/pub/linux/kernel/people/brodo/temp-...
I'm still undecided on what to do with these userspace tools. IMO they could
either be merged into pcmcia-cs or distributed in addition to pcmcia-cs.
Also,
I'd be very glad if somebody else could maintain and improve these tools.
pcmcia-socket-startup
This tool is based on "cardmgr" by Dave Hinds, but most of it was removed.
The
remains parse the /etc/pcmcia/config file for allowed ioport and iomem ranges
and for disallowed IRQs, and sets these using libsysfs. Due to a bug in
libsysfs, a patch is needed for this to work properly. It takes one
parameter,
the socket number to be set up.
pcmcia-modalias
This tool reads device information and generates a MODALIAS string just like
the kernel exports using hotplug for this device. It takes one paramter, the
device's bus_id string (e.g. "pcmcia-modalias 1.0" for the first device on
the
second PCMCIA socket)
pcmcia-check-broken-cis
This checks whether the CIS is so broken that only the "tuple"-based match is
possible. It takes one parameter, the socket the PCMCIA card to be tested is
inserted to, and returns nothing (if no CIS override is needed), or the CIS
file name. The CIS parsing is done using a much simplified version of what
is to be found in drivers/pcmcia/cistpl.c, so this is based on Dave Hinds
work as well.
hotplug/pcmcia*
The hotplug scripts are quite self-explanatory and also allow for "coldplug"
(i.e. they work around "missed" events during boot).
pccardctl
This previously announced tool uses sysfs instead of an ioctl for commands
like "eject", "insert", "info" and "ident".
[*] reason: they're partly based on other GPL-licensed tools.
This patch:
Don't inform cardmgr of ejection requests so that "cardctl eject" behaves
_exactly_ the same as a physical ejection from an userspace point of view.
Removing this allows us to clean up some other code which is otherwise
unused.

[PATCH] ppc64: fix AIO panic on PPC64 caused by is_hugepage_only_range()
When testing AIO on PPC64 (a power5 machine) running 2.6.11 with
CONFIG_HUGETLB_PAGE=y, I ran into a kernel panic when a process exits that
has
done AIO (io_queue_init()) but has not done the io_queue_release(). The
exit_aio() code is cleaning up and panicking when trying to free the aio ring
buffer.
I tracked this down to is_hugepage_only_range() (include/asm-ppc64/page.h)
which is doing a touches_hugepage_low_range() which is checking
current->mm->context.htlb_segs. The problem is that exit_mm() cleared
tsk->mm
before doing the mmput() which leads to the exit_aio() and then the panic.
Looks like is_hugepage_only_range() is only used in ia64 and ppc64. Fix is
to
change is_hugepage_only_range() to take an 'mm' as a parameter as well as
'addr' and 'len' and then the ppc64 code could change to use 'mm'. It looks
like it has been broken for quite a while.

[PATCH] mm counter operations through macros
This patch extracts all the operations on counters protected by the page
table lock (currently rss and anon_rss) into definitions in
include/linux/sched.h. All rss operations are performed through the
following macros:
get_mm_counter(mm, member) -> Obtain the value of a counter
set_mm_counter(mm, member, value) -> Set the value of a counter
update_mm_counter(mm, member, value) -> Add to a counter
inc_mm_counter(mm, member) -> Increment a counter
dec_mm_counter(mm, member) -> Decrement a counter
With this patch it becomes easier to add new counters and it is possible to
redefine the method of counter handling. The counters are an issue for
scalability since they are used in frequently used code paths and may cause
cache line bouncing.
F.e. One may not use counters at all and count the pages when needed, switch
to atomic operations if the mm_struct locking changes or split the rss
into counters that can be locally incremented.
The relevant fields of the task_struct are renamed with a leading underscore
to catch out people who are not using the acceessor macros.

This patch cleans up asm-*/pgalloc.h by removing the generous includes
which are obsoleted (duplicated) by including linux/mm.h (and friends)
They are double checked and verified by the PLM cross compiling service
(the patched kernel gives the same warnings/errors as the unpatched)

[PATCH] unused 'size' assignment in filemap_nopage
filemap_nopage has the following code:
retry_all:
size = (i_size_read(inode) + PAGE_CACHE_SIZE - 1) >> PAGE_CACHE_SHIFT;
if (pgoff >= size)
goto outside_data_content;
/* If we don't want any read-ahead, don't bother */
if (VM_RandomReadHint(area))
goto no_cached_page;
/*
* The "size" of the file, as far as mmap is concerned, isn't bigger
* than the mapping
*/
if (size > endoff)
size = endoff;
After this, size is not referenced. So, either this potential reassignment
of size is superfluous, or we are missing some other code later on in the
function. If it is the former, I've attached a patch which will remove the
code.
(akpm: and endoff can go away too. That was the unused variable which gcc
has
been warning about for ages. Also, gratuitous whitespace fiddling).

[PATCH] ppc32: Fix Sandpoint Soft Reboot
This patch allows the Freescale Sandpoint to perform soft reboots. A write
of 0x00 to the Winbond's Chip Select Control Register was clearing the
Upper BIOS Chip Select Enable bit which unmaps the boot flash. The comment
associated with the write noted that it was enabling the RTC and Keyboard
address locations, but the bits in question (1 and 0) are reserved when the
Winbond chip is in PowerPC mode. Also, the bits are 1 for enable, 0 for
disable, therefore the original code was actually disabling the address
locations. The patch also corrects errors in the definitions of 2
configuration bits in the Tundra Tsi107 bridge's MAPB Options register.

[PATCH] ppc32/64: Map prefetchable PCI without guarded bit
While experimenting with framebuffer access performances, we noticed a very
significant improvement in write access to it when not setting the
"guarded" bit on the MMU mappings. This bit basically says that reads and
writes won't have side effects (it allows speculation). It appears that it
also disables write combining.
This patch implements a new phys_mem_access_prot() arch callback for use by
/dev/mem and fbdev when available, implements it for ppc32 and ppc64, and
modifies /dev/mem and fbdev to use it, respectively when available or on
ppc. I didn't change fbdev to use it on all archs when available because
there is already a whole lot of arch specific mess in there (more than in
/dev/mem !) that I didn't feel like messing with, but archs maintainers are
welcome to give it a go).
The old mechanism in /dev/mem is still there, but arch maintainers should
probably switch to this once which is more consistent imho.
Finally, the ppc32 and ppc64 implementation of this and of the PCI mmap
calls (used by /proc and /sys) are modified to check if the mapping happens
in a prefetchable PCI resource, in which case, the guarded bit is not set
for the pgprot. In fact, ppc32 implementation of this code is updated to
be identical to ppc64.
This improves framebuffer write performance on a simple test paul wrote
from about 50Mb/sec to 200Mb/sec on my M9 based laptop and on a G5. The
new hook will automatically catch up Xfree mmap's from /dev/mem, so it will
work out of the box with existing X servers. Kernel fbdev accesses aren't
improved yet as ioremap doesn't use that mecanism.

[PATCH] x86: CMOS time update optimisation
This patch changes the update of the cmos clock to be timer driven rather
than poll driven by the timer interrupt function. If the clock is not
being synced to an outside source the timer is removed and thus system
overhead is nill in that case. The update frequency is still ~11 minutes
and missing the update window still causes a retry in 60 seconds.
We want the calls to sync_cmos_clock() to be made in a consistent
environment.
This was not true when calling it directly from the NTP call code. The
change means that sync_cmos_clock() is ALWAYS called from run_timers(), i.e.
as a timer call back function.
Also, call the timer code only through the timer interface (set a short timer
to do it from the ntp call).

[PATCH] x86_64: Work around Tyan BIOS MTRR initialization bug.
Work around Tyan BIOS MTRR initialization bug.
Some Tyan AMD BIOS don't initialize the first fixed range MTRR, which causes
it to contain random bogus values. When the MTRR tries to duplicate the MTRR
state to other CPUs at startup it oopses because of this.
This patch works around this by catching exception while setting MTRRs.
It would be better to validate all fixed range MTRRs and fix them, but that
would be very complicated code. This simple hack seems to work too (except
that the first 64k of physical memory are likely uncached). A BIOS update
fixes that.

[PATCH] x86_64: Fix NMI RTC access race
Fix NMI RTC access race
This patch fixes a race between the CMOS clock setting and the NMI code. 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.
Resetting the NMI is not required on x86_64 (in fact, it should not be done
according to the ICH5 documentation). This patch simply removes the useless
code.

[PATCH] uml: fix "cond. expr. as lvalues" warning
Gcc 3.4.3 (and probably any 3.4) emits some "deprecation" warnings currently
about usages of CHOOSE_MODE, since the below syntax has been deprecated:
(a ? foo: bar) = foobar;
which often results from expansion of:
CHOOSE_MODE(foo, bar) = foobar;
So add an additional __CHOOSE_MODE syntax for users which need to get a
lvalue, which uses (a ? &foo : &bar) inside a function, casts the result to
the correct type and dereference the pointer, and use it where needed (i.e.
in <sysdep/ptrace.h>)
The patch builds and runs correctly (this has been tested on i386 only, not
on
x86_64), and removes all the warnings.

[PATCH] Can't unmount bad inode
This patch fixes a problem when a inode which is the root of a mount
becomes bad (make_bad_inode()). In this case follow_link will return
-EIO, so the name resolution fails, and umount won't work. The
solution is just to remove the follow_link method from bad_inode_ops.
Any filesystem operation (other than unmount) will still fail, since
every other method returns -EIO.
A test case for this is:
1) export an smbfs on host A and mount the share on host B
2) create directory X on A under the exported directory
3) bind mount X to Y on B (Y need not be under the share)
4) remove directory X, and create regular file X (same name) on A
5) stat X on B, this will make X a bad inode (file type changed)
6) umount Y
Without the patch applied, umount won't succeed, and a reboot is
necessary to get rid of the mount.
With the patch applied, umount will succeed.
The same is true for any filesystem which uses make_bad_inode() to
mark an existing inode bad (NFS, SMBFS, FUSE, etc...).

[PATCH] break_lock fix
lock->break_lock is set when a lock is contended, but cleared only in
cond_resched_lock. Users of need_lockbreak (journal_commit_transaction,
copy_pte_range, unmap_vmas) don't necessarily use cond_resched_lock on it.
So, if the lock has been contended at some time in the past, break_lock
remains set thereafter, and the fastpath keeps dropping lock unnecessarily.
Hanging the system if you make a change like I did, forever restarting a
loop before making any progress. And even users of cond_resched_lock may
well suffer an initial unnecessary lockbreak.
There seems to be no point at which break_lock can be cleared when
unlocking, any point being either too early or too late; but that's okay,
it's only of interest while the lock is held. So clear it whenever the
lock is acquired - and any waiting contenders will quickly set it again.
Additional locking overhead? well, this is only when CONFIG_PREEMPT is on.
Since cond_resched_lock's spin_lock clears break_lock, no need to clear it
itself; and use need_lockbreak there too, preferring optimizer to #ifdefs.

[PATCH] Fix irq_affinity write from /proc for ia64
Made GENERIC_HARDIRQ mechanism work for ia64 and CPU hotplug. When write
to /proc/irq is handled it is not appropriate to perform set_rte
immediatly, since there is a race when the interrupt is asserted while the
re-program is happening. Hence such programming is only safe when we do
the re-program at the time of servicing an interrupt. This got broken when
GENERIC_HARDIRQ got introduced for ia64.
- added CONFIG_PENDING_IRQ so default /proc/irq write handler can do the
right
thing.
TBD: We currently dont handle redirectable hint either in the display, or
when we handle writes to /proc/irq/XX/smp_affinity. We need an arch
specific way to account for the presence of "r" hint when we handle the
proc write.

It's better than early printk because it unregisters automatically when a

console_init, there isn't a huge delay between the boot console
unregistering and the real console starting. This is the case on PA-RISC
where we have serial ports that aren't discovered until the PCI bus has
been walked.

[PATCH] posix-cpu-timers and cputime_t divisons.
The posix cpu timers introduced code that will not work with an arbitrary
type for cputime_t. In particular the division of two cputime_t values
broke the s390 build because cputime_t is define as an unsigned long long.
The first problem is the division of a cputime_t value by a number of
threads. That is a cputime_t divided by an integer. The patch adds
another macro cputime_div to the cputime macro regime which implements this
type of division and replaces all occurences of a cputime / nthread in the
posix cpu timer code.
Next problem is bump_cpu_timer. This function is severly broken:
1) In the body of the first if statement a timer->it.cpu.incr.sched is
used as the second argument of do_div. do_div expects an unsigned long
as "base" parameter but timer->it.cpu.incr.sched is an unsigned long
long. If the timer increment ever happens to be >= 2^32 the result is
wrong and if the lower 32 bits are zero this even crashes with a fixed
point divide exception.
2) The cputime_le(now.cpu, timer->it.cpu.expires.cpu) in the else if
condition is wrong. The cputime_le() reads as "now.cpu <=
timer->it.cpu.expires.cpu" and the subsequent cputime_ge() reads as
"now.cpu >= timer.it.cpu.expires.cpu". That means that the two values
needs to be equal to make the body of the second if to have any effect.
The first cputime_le should be a cputime_ge.
3) timer->it.cpu.expires.cpu and delta in the else part of the if are of
type cputime_t. A division of two cputime_t values is undefined (think
of cputime_t as e.g. a struct timespec, that just doesn't work). We
could add a primitive for this type of division but we'd end up with a
64 bit division or something even more complicated.
The solution for bump_cpu_timer is to use the "slow" division algorithm
that does shifts and subtracts. That adds yet another cputime macro,
cputime_halve to do the right shift of a cputime value.
The next problem is in arm_timer. The UPDATE_CLOCK macro does the wrong
thing for it_prof_expires and it_virt_expires. Expanded the macro and
added the cputime magic to it_prof/it_virt.
The remaining problems are rather simple, timespec_to_jiffies instead of
timespec_to_cputime and several cases where cputime_eq with cputime_zero
needs to be used instead of "== 0".
What still worries me a bit is to use "timer->it.cpu.incr.sched == 0" as
check if the timer is armed at all. It should work but its not really
clean.

[PATCH] ext2/3 file limits to avoid overflowing i_blocks
As discussed before, we can overflow i_blocks in ext2/ext3 inodes by
growing a file up to 2TB. That gives us 2^32 sectors of data in the file;
but once you add on the indirect tree and possible EA/ACL metadata,
i_blocks will wrap beyond 2^32. Consensus seemed to be that the best way
to avoid this was simply to stop files getting so large that this was a
problem in the first place; anything else would lead to complications if a
sparse file tried to overflow that 2^32 sector limit while filling in
holes.
I wrote a small program to calculate the total indirect tree overhead for
any given file size, and 0x1ff7fffe000 turned out to be the largest file we
can get without the total i_blocks overflowing 2^32.
But in testing, that *just* wrapped --- we need to limit the file to be one
page smaller than that to deal with the possibility of an EA/ACL block
being accounted against i_blocks.
So this patch has been tested, at least on ext3, by letting a file grow
densely to its maximum size permitted by the kernel; at 0x1ff7fffe000, stat
shows the file to have wrapped back exactly to 0 st_blocks, but with the
limit at 0x1ff7fffd000, du shows it occupying the expected 2TB-blocksize
bytes.

[PATCH] io_remap_pfn_range: add for all arch-es
This patch introduces a new interface function for mapping bus/device memory:
io_remap_pfn_range. This accepts the same parameters as remap_pfn_range and
io_remap_page_range but should be used in any situation where the caller is
not simply remapping ordinary RAM. For example, when mapping device
registers
the new function should be used.
The distinction between remapping device memory and ordinary RAM is critical
for the Xen hypervisor.
This patch series also cleans up the remaining users of io_remap_page_range
(in particular, the several sparc-specific sections in various drivers that
use a special form of io_remap_page_range: an extra <iospace> argument for
SPARC arch.) by converting them to use io_remap_pfn_range(), where
io_remap_pfn_range() supports passing <iospace> as part of the pfn argument.
The sparc32 & sparc64 code needs live testing.
(from Keir:)
I have audited the drivers/ and sound/ directories. Most uses of
remap_pfn_range are okay, but there are a small handful that are remapping
device memory (mostly AGP and DRM drivers).
Of particular driver is the HPET driver, whose mmap function is broken even
for native (non-Xen) builds. If nothing else, vmalloc_to_phys should be
used
instead of __pa to convert an ioremapped virtual address to a valid physical
address. The fix in this patch is to remember the original bus address as
probed at boot time and to pass this to io_remap_pfn_range.
io_remap_pfn_range():
add io_remap_pfn_range() for all arches;
add MK_IOSPACE_PFN(), GET_IOSPACE(), and GET_PFN()
for all arches but primarily for sparc32/64's extended IO space,
sparc: kill the hack of using low bit of <offset> to mean
write_combine or set side-effect (_PAGE_E) bit;
(DaveM suggested that I kill it;)

[PATCH] arch hook for notifying changes in PTE protections bits
Recently on IA-64, we have found an issue where old data could be used by
apps. The sequence of operations includes few mprotects from user space
(glibc) goes like this:
1- The text region of an executable is mmaped using
PROT_READ|PROT_EXEC. As a result, a shared page is allocated to user.
2- User then requests the text region to be mprotected with
PROT_READ|PROT_WRITE. Kernel removes the execute permission and leave
the read permission on the text region.
3- Subsequent write operation by user results in page fault and
eventually resulting in COW break. User gets a new private copy of the
page. At this point kernel marks the new page for defered flush.
4- User then request the text region to be mprotected back with
PROT_READ|PROT_EXEC. mprotect suppport code in kernel, flushes the
caches, updates the PTEs and then flushes the TLBs. Though after
updating the PTEs with new permissions, we don't let the arch specific
code know about the new mappings (through update_mmu_cache like
routine). IA-64 typically uses update_mmu_cache to check for the
defered flush flag (that got set in step 3) to maintain cache coherency
lazily (The local I and D caches on IA-64 are incoherent).
DavidM suggeested that we would need to add a hook in the function
change_pte_range in mm/mprotect.c This would let the architecture specific
code to look at the new ptes to decide if it needs to update any other
architectual/kernel state based on the updated (new permissions) PTE
values.
We have added a new hook lazy_mmu_prot_update(pte_t) that gets called
protection bits in PTEs change. This hook provides an opportunity to arch
specific code to do needful. On IA-64 this will be used for lazily making
the I and D caches coherent.

- combo cards with parallel are erroneously claimed by serial driver
- serial and parport_serial blindly probe for ports

parport_serial:
Previously supported 9735 and 9835. Add 9745, 9845, 9855, and
add init hooks to discover how many serial/parallel ports are
actually present (the boards are available in various configs).
Add protection for overflow of static tables.
quirks:
Detect Netmos combo (parallel + serial) cards and change class from
SERIAL to OTHER to prevent serial driver from claiming them.

[PATCH] ext3/jbd race: releasing in-use journal_heads
Fix destruction of in-use journal_head
journal_put_journal_head() can destroy a journal_head at any time as
long as the jh's b_jcount is zero and b_transaction is NULL. It has no
locking protection against the rest of the journaling code, as the lock
it uses to protect b_jcount and bh->b_private is not used elsewhere in
jbd.
However, there are small windows where b_transaction is getting set
temporarily to NULL during normal operations; typically this is
happening in
__journal_unfile_buffer(jh);
__journal_file_buffer(jh, ...);
call pairs, as __journal_unfile_buffer() will set b_transaction to NULL
and __journal_file_buffer() re-sets it afterwards. A truncate running
in parallel can lead to journal_unmap_buffer() destroying the jh if it
occurs between these two calls.
Fix this by adding a variant of __journal_unfile_buffer() which is only
used for these temporary jh unlinks, and which leaves the b_transaction
field intact so that we never leave a window open where b_transaction is
NULL.
Additionally, trap this error if it does occur, by checking against
jh->b_jlist being non-null when we destroy a jh.

[PATCH] ext3: fix journal_unmap_buffer race
There is a race condition in jbd between journal_unmap_buffer() and
journal_commit_transaction(). This is leading to corruption of buffers on
the
transaction's t_locked_list, leading to a variety of symptoms usually
involving an oops in kjournald.
The problem is that various special-case exit paths in journal_unmap_buffer()
call journal_put_journal_head without any locking. This is racing against a
refiling of the same journal_head in journal_commit_transaction():
__journal_unfile_buffer(jh);
__journal_file_buffer(jh, commit_transaction,
BJ_Locked);
The way these functions work, this leaves the jh temporarily with
b_transaction==NULL; and if journal_unmap_buffer()'s call to
journal_put_journal_head() hits this window, it sees the NULL transaction and
frees the journal_head which is just about to get refiled on the locked list.
The main exit path on journal_unmap_buffer() performs its
journal_put_journal_head() before dropping the j_list_lock, so is not
vulnerable to this race. The fix is to move the other similar calls on
special-case exit branches in that function so that they also release the
journal_head before dropping that lock.
This is low-risk since the new order has already been tested as the normal
exit path from this function. The change has had extensive testing and has
been shown to fix the problem with no regressions found.

[PATCH] fix fc class work queue usage
According to this article http://lwn.net/Articles/125930/, "When
cancel_delayed_work() returns zero, it means that the delayed
work request was fired off before the call; it might, in fact,
be running on another CPU when the cancel attempt is made".
If it is successful, it returns a nonzero value. Tracing
through cancel_delayed_work's timer usage would seem to confirm
this. The fc class today though performs a flush_scheduled_work,
when the return value is nonzero instead of zero.
Also it appears the fc class will use flush_scheduled_work to
flush the work from the shost_work_q when it should be using
flush_workqueue(shost->work_q) (flush_scheduled_work() only
flushes the default, keventd_wq, work queue).
The attached patch adds a scsi_flush_work function for
scsi_transport_fc to use and it fixes the cancel_delayed_work()
test to detect when to flush the work queues correctly (it
also only calls cancel_delayed_work when the work is queued
as delayed (scan_work is not delayed).

[PATCH] USB: add driver for CP2101/CP2102 RS232 adaptors
This patch against 2.6.10 provides the driver for the CP2101 and CP2102
USB to RS232 adaptor chips which are found in some serial converter
cables and usb mobile phone cables.
It provides cp2101.c, and patches Kconfig and Makefile in
drivers/usb/serial Since there is no technical data sheet freely
available for these chips, much of the code in this driver has been
based on protocol analysis, assumptions and guesswork.
The cp210x family of devices have OEM programmable device IDs so updates
will be required as and when new devices are found.
The driver currently only supports configuration of baud rate, data
bits, stop bits and parity mode. While this is enough to enable the use
of a wide range of devices based on this chip, the driver is still
incomplete in many areas such as flow control. Unfortunately without
technical datasheets, implementing these features is made very difficult
indeed.

[PATCH] USB: ohci D3 resume fix
This fixes a problem that cropped up resuming OHCI from PCI D3 on
NForce2. Evidently the register controlling frame timing gets
clobbered in D3, but not other registers ... a "by the book" reinit
seems to solve this particular problem. (And ought to help a few
startup glitches on other implementations. Linux never used that
toggle bit before, and has had to struggle with glitchy init...)
It also updates some diagnostics to be bit more useful, and tries
to avoid a particular "wakeup while suspending" glitch that seems
particular to one particular type of Australian mouse.

Fix SCSI internal requests hang
When a device is being torn down (mostly in USB ejection)
we hit conditions where SCSI hangs in wait_for_completion().
The reason is that the scsi request prep function does a
state check on the device and rejects it with BLKPREP_KILL if
we're in the DEL (going away, no more I/O) state.
Unfortunately, I/O submitted by scsi_wait_req() doesn't have
its request->end_io initialised, so we're never notified of
this (the submit path expects everything to come back via
the scsi_request->sr_done() routine, which only happens
if the I/O actually gets submitted.
Note: almost everything that uses scsi_do_request() is wrong
not only in this regard but also on other things, like ending
tags.

There is no 'ports' parameter for the ip_nat_ftp and ip_nat_irc modules in

unfortunate that we were lazy in the original implementation, and forced
the user to duplicate the arguments.
Even more unfortunate, the removal of the parameter caused autoloading to

solution is to restore the parameter as a dummy, with a polite warning

3. Add an additional PCI device id to support Neterion's new Xframe II.
Some background info on Xframe-II, just in case -
The NIC was announced back in January (see
http://www.serverwatch.com/news/article.php/3464871)
Xframe II is a PCI-X 2.0 DDR adapter designed to work in PCI-X 2.0 servers
(it is also backwards compatible with current pci-x and pci slots); it's a
first card to overcome pci-x 133 throughput bottleneck. Some of these pci-x
2.0 servers are available now and more are coming later in the year.
Xframe II is completely backward compatible and hence the current driver
will work as-is, except the device id change.
There are some additional features/stateless offloads in Xframe-II
as well; we plan to submit patches for these soon.

This is possible because netlink_dump isn't always called from the
context of the process that owns the socket. For instance, if there
is contention on rtnl then rtnetlink requests will be processed by

It's a one line fix, where some config registers get corrupted during

This bug was introduced somewhere betweeen 2.4.17 and 2.6.x (noticed

(*) BDI_CAP_NO_WRITEBACK

(*) Capability markers that indicate what a backing device is capable of
with regard to memory mapping facilities. These flags indicate whether
a
device can be mapped directly, whether it can be copied for a mapping,
and whether direct mappings can be read, written and/or executed. This
information is primarily aimed at improving no-MMU private mapping

[PATCH] ppc32: MPC8555 CPM2 size/pointers for FCCs aka "All-ones problem"
I've seen that MPC8555 support also made it into linux-2.6 by now.
I don't have hardware and time to test, but it looks like this bug has made
it over from the linuxppc-2.4 tree. The 8541/8555 has a smaller CPM DPRAM
than the standard CPM2, just like the 8272.
Unfortunately, the manual recommends you to use a segment of CPM DPRAM that
is not implemented in the 8541/55. If the smaller DPRAM is not taken into
account, fcc_enet.c will initialise the internal CPM buffer pointers
(fcc_riptr/fcc_tiptr) to invalid offsets, with the result that all the FCC
will ever send and receive are 0xff-en.

but it's an optimization in the slow path, and current code is a bit

[PATCH] ppc64: Add mem=X boot command line option
This patch adds the mem=X boot command line option for PPC64.
On iSeries the user's mem=X value is aligned to PAGE_SIZE, on pSeries we
align to 16 MB which is the size of a large page.
The iSeries implementation is fairly straight forward, we declare mem=X as
an early_param() and then in iSeries_init_early() we modify the
systemcfg->physicalMemorySize based on that value.
On pSeries the mem=X option is parsed in prom_init.c before the kernel
proper starts, and is used to modify prom_init_mem()'s idea of memory. The
mem=X value and computed tce_alloc_start/end values are saved by
prom_init() into the device tree for later use by the kernel.
The device tree properties are read by the kernel in
early_dt_scan_chosen(), and used to modify the lmb structure in
early_init_devtree(). That's the guts of it.
On non-LPAR machines the tce_alloc_start/end values are read from the
device tree and used in htab_initialize() to make sure the TCE table is
mapped at the real top of RAM.
If NUMA is enabled we also have to make changes in parse_numa_properties()
and do_init_bootmem() to exclude memory regions above the memory limit, and
truncate any region which stradles the limit.
NB. This patch does not facilitate using mem=X to give drivers access to
large regions of contiguous memory.

Later, Andrea said:
While this still seems a needed fix, unfortunately this wasn't enough to
fix the problem (the first positive report I got was because they did a
mistake and they tested an UP kernel, oh well ;).
Anyway the smp_stop_cpu executed by the cpu that invoked panic is wrong
and it really causes an underflow of the number of cpus that can lead to
further lockups. So I don't want to stop you from merging it since it
seems a correct fix and it brings x86-64 in line with the x86 code too.
But apparently we need something more than this too.

[PATCH] x86-64 kprobes: handle %RIP-relative addressing mode
The existing x86-64 kprobes implementation doesn't cope with the
%RIP-relative addressing mode. Kprobes work by single-stepping a copy of
an instruction overwritten by a breakpoint. When a probe is inserted on an
instruction that uses the %RIP-relative data addressing mode, the copy run
in a different location gets different data and so the presence of that
probe causes the probed code to read or write the wrong memory location.
Without this problem fixed, it is woefully unsafe to use the current
kprobes code on x86-64 unless you are sure the instruction you instrument
is not one that accesses global data using the %RIP addressing mode.
This patch fixes the problem by recognizing the %RIP-relative addressing
mode in an instruction when it's being copied to insert the kprobe, and
adjusting its displacement so that it finds the right data. Taking this
approach requires that the copied instruction's %RIP value be within 2GB of
the virtual address of the data, i.e. the text/data areas of the kernel
code and loaded modules. To satisfy this need the patch also replaces the
use of vmalloc for getting instruction pages with lower-level calls to use
a different part of the address space, the area at the top of the address
space just above where modules are loaded. I left one page of red zone at
the top, and the 1MB-4KB thus available allows for at most 69632 kprobes.
(If we ever need to overcome that limit, we can change this to add a hook
into the arch/x86_64/kernel/modules.c code and allocate pages inside the
module area loading area instead.)

[PATCH] x86, x86_64: reading deterministic cache parameters and exporting it in
/sysfs
The attached patch adds support for using cpuid(4) instead of cpuid(2), to
get CPU cache information in a deterministic way for Intel CPUs, whenever
supported. The details of cpuid(4) can be found here
IA-32 Intel Architecture Software Developer's Manual (vol 2a)
(http://developer.intel.com/design/pentium4/manuals/index_...)
and
Prescott New Instructions (PNI) Technology: Software Developer's Guide
(http://www.intel.com/cd/ids/developer/asmo-na/eng/events/...)
The advantage of using the cpuid(4) ('Deterministic Cache Parameters Leaf')
are:
- It provides more information than the descriptors provided by cpuid(2)
- It is not table based as cpuid(2). So, we will not need changes to the
kernel to support new cache descriptors in the descriptor table (as is
the case with cpuid(2)).
The patch also adds a bunch of interfaces under
/sys/devices/system/cpu/cpuX/cache, showing various information about the
caches. Most useful field being shared_cpu_map, which says what caches are
shared among which logical cpus.
The patch adds support for both i386 and x86-64.

[PATCH] uml: quick fix syscall table
*) Uml 2.6.11 does not compile with gcc 2.95.4 because some entries are
duplicated, and that GCC does not accept this (unlike gcc 3). Plus various
other bugs in the syscall table definitions:
*) 223 is a syscall hole (i.e. ni_syscall) only on i386, on x86_64 it's a
valid syscall (thus a duplicated one).
*) __NR_vserver must be only once with sys_ni_syscall, and not multiple
times with different values!
*) syscalls duplicated in SUBARCHs and in common files (thus assigning
twice
to the same array entry and causing the GCC 2.95.4 failure mentioned
above):
sys_utimes, which is common, and sys_fadvise64_64, sys_statfs64,
sys_fstatfs64, which exist only on i386.
*) syscalls duplicated in each SUBARCH, to put in common files:
sys_remap_file_pages, sys_utimes, sys_fadvise64
*) 285 is a syscall hole (i.e. ni_syscall) only on i386, on x86_64 the
range
does not arrive to that point.
*) on x86_64, the macro name is __NR_kexec_load and not
__NR_sys_kexec_load.
Use the correct name in either case.
Note: as you can see, part of the syscall table definition in UML is
arch-independent (with everywhere defined syscalls), and part is
arch-dependant. This has created confusion (some syscalls are listed in both
places, some in the wrong one, some are wrong on one arch or another).
Also, as add-ons:
*) uses __va_copy instead of va_copy since some old versions of gcc (2.95.4
for instance) don't accept va_copy.
*) some whitespace cleanups in the syscall table (if you don't like them,
feel
free to remove them).

[PATCH] uml: Fix the console stuttering
I spent far too much of the weekend tracking this sucker down through the
guts
of the tty code. The problem turns out to be that drivers/char/n_tty.c has a
write_chan that does buffering and retransmitting data, and
arch/um/drivers/chan_kern.c ALSO has a write_chan that buffers and
retransmits
data, and the first calls the second but the second doesn't always return
correct status information for the -EAGAIN case.
When they get confused, both of them try to buffer and retransmit data, hence
the stuttering.
The first fix is that if chan_kern's write_chan gets an -EAGAIN, it should
NOT
gratuitously change that to a 0 before returning. I don't know why that code
is in there, but deleting those two lines makes 90% the stuttering go away.
But not quite all of it.
The second half of the fix is arch/um/drivers/line.c has a buffer_data()
function that adds data to the buffer, tries to flush the buffer out to disk,
gets -EAGAIN, and then returns -EAGAIN even though it successfully buffered
all the data it was sent. So the upper layer resubmits the last chunk of
data
it sent when the console unblocks, even though the lower layer buffered it
and
sent it on by that point.
With this patch, I can't get the UML console to stutter anymore by suspending
the process it's writing to. (Add tee to the mix and you can still make it
hang by suspending its xterm for a second or two, but I think that tee is
hanging, not UML. Hangs with RHEL4 tee, but not busybox tee...)

[PATCH] Kprobes: Allow/deny probes on int3/breakpoint instruction?
Kprobes did an improper exit when a probe is inserted on an int3
instruction. In case of normal execution of int3/breakpoint instruction,
it oops!. Probe on an int3 instruction was not handled properly by the
kprobes, it generated faults after oops! doing an improper exit with
holding the lock. This fix employes a bit different method to handle probe
on an int3/breakpoint instruction.
On execution of an int3/breakpoint instruction (placed by kprobe),
kprobes_handler() is called which sets it for single stepping in-line(it
does not matter whether we single step out-of-line/inline since the single
stepping instruction is same). Now it single steps on int3/breakpoint
instruction here, entering kprobes_handler() once again. Kprobes now
check's the status that it is single stepping and avoids the recursion. It
runs down through the trap handler and oops messages is seen on the console
since it executed int3/breakpoint instruction. Here the kprobes single
stepping handler never gets called.
Is this behaviour acceptable ? Or should we avoid putting probes on an
int3 /breakpoint instruction ? How should it handle such situations?
Below is the patch to allow probes on an int3/breakpoint instruction.
This patch fixes the above problem by doing a proper exit while avoiding
recursion.

[PATCH] vt: don't call unblank at irq time
This patch removes the call to unblank() from printk, and avoids calling
unblank at irq() time _unless_ oops_in_progress is 1. I also export
oops_in_progress() so drivers who care like radeonfb can test it and know
what to do. I audited call sites of unblank_screen(), console_unblank(),
etc... and I _hope_ I got them all, the patch includes a small patch to
the s390 bust_spinlocks code that sets oops_in_progress back to 0 _after_
unblanking for example.
I added a few might_sleep() to help us catch possible remaining callers.
I'll soon write a document explaining fbdev locking. The current situation
after this patch is that:
- All callbacks have console_semaphore held (fbdev's are fully
serialised).
- Everything is called in schedule'able context, except the cfb_*
rendering operations and cursor operations, with the special case of
unblank who can be called at any time when "oops_in_progress" is true. A
driver that needs to sleep in it's unblank implementation is welcome to
test that variable and use a fallback path (or just do nothing if it's
not simple).

[PATCH] ppc32: move powermac backlight stuff to a workqueue
The powermac has a kernel-based driver for controlling the backlight from
the keyboard that used to call into some fbdev's from interrupt contexts.
This patch moves it to a workqueue (and additionally makes sure the console
semaphore is taken and held).
I hope I'll replace this by the new backlight framework in a future kernel
version, but for now, this will fix the immediate issues with radeon.

[PATCH] radeonfb: Implement proper workarounds for PLL accesses
After discussion with ATIs, it seems that the workarounds they initially gave
me were not completely correct.
This patch implements the proper ones, which includes sleeping in PLL
accesses, and thus requires the previous patch to make sure we do not call
unblank at interrupt time (unless oops_in_progress is set, in which case I
use
an mdelay).
It also removes obsolete code that used to disable some power management
features in the accel init code.

[PATCH] fbcon: Stop framebuffer operations before hardware is properly
initialized
Accessing the hardware before it is properly initialized can lead to crashes
or screen corruption. This happens when switching to X then back to console.
When console comes back from X, the device is in an undefined state. During
this window, accessing the hardware is disallowed.
A new field in fbcon_par is added (graphics), which will be set to nonzero
just before initialization of the framebuffer and when coming back from
KD_GRAPHICS, then unset when an fb_set_var/fb_set_par is done. While this
field is set, no accesses to the hardware is done. The consequence of this
change is, hopefully, more robust switching between KD_GRAPHICS<-> KD_TEXT.
An added benefit coming from this change is that the MODESWITCHLATE hack is
not needed anymore and thus removed. This hack is used by savagefb, rivafb
and nvidiafb.

This driver has been succesfully tested on ARM embedded boards and reported
working on SH architecture as well.
Since this is my first framebuffer driver, I would welcome any
suggestion/comment about it :)
This driver has been built on top of some preliminary ARM specific work by

[PATCH] I2C: New lm92 chip driver
This is a new i2c chip driver named lm92. It supports the National
Semiconductor LM92 and Maxim MAX6635 chips. This time I did not port the
driver from the lm_sensors project but instead rewrote it. The reason is
that the original driver has a different structure from the other i2c
chip drivers, which would have made maintenance harder.
I don't have a compatible chip myself but could test my code thanks to
Mark Hoffman's i2c-stub fake bus driver. Later on, James Chapman tested
it on a real chip, successfully.

[PATCH] I2C: Skip broken detection step in it87
One of the detection steps in the it87 chip driver was reported to be
broken for some revisions of the IT8712F chip [1] [2]. This detection
step is a legacy from the lm78 driver and the documentation available
for the IT8705F and IT8712F chips does not mention it at all. For this
reason, I propose to skip this detection step for Super-I/O chips.
Super-I/O chips have already been identified when we reach this step, so
it is redundant (additionally do being broken). This closes bug #4335.

[PATCH] I2C: Kill outdated defines in i2c.h
Some defines in i2c.h (I2C_CLIENT_MODPARM and friends) are now useless.
They should have been removed when the i2c client parameters were
converted from MODULE_PARAM to module_parm_array, but where not. This
patch removes them now.
Additionally, it moves the definition of I2C_CLIENT_MAX_OPTS next to
where it is used rather than 220 lines before, which is preferable IMHO.
As a side note, I think that there is a bug in the way these options are
handled. The i2c code looks for I2C_CLIENT_END as a list terminator, but
if the maximum number of parameters are actually provided, no terminator
will be left. It's rather unlikely to happen because nobody will
probably ever provide that many parameters, but this should probably be
fixed. I'll address this issue later, since I plan to completely rewrite
the way these parameters are handled anyway.

[PATCH] I2C: Avoid repeated resets of i2c-viapro
It was reported that the i2c-viapro SMBus driver sometimes has trouble
on recent systems (VT8237 south bridge). The "Host Status" register has
at least one additional bit used when compared with older south bridges
of this family. The driver currently considers this additional bit as an
error condition when it's set, causing repeated bus resets and sometimes
read failures.
This patch makes the driver ignore the bits of the "Host Status"
register for which no definition is known. I wish I had a datasheet for
the VIA VT8237, so that I could check what the additional bit is
supposed to mean, but I don't. If someone has a datasheet or good
contacts at VIA, please let me know.
The patch was reported to fix the problem on a system with the VT8237,
and was also tested not to break the driver on older VIA south bridges,
so it seems to be safe. Thanks to Aurelien Jarno for the tests.
Additionally, the patch makes the post-transaction bus reset slightly
more efficient by sparing a few unneeded I/O operations.

This patch provides lost arbitration detection for the PCF8584

callers may detect this condition explicitly. LAB could be checked

[PATCH] I2C: Fix broken force parameter handling

with the current code, the second and third pairs wouldn't be properly

[IPSEC]: Move xfrm_flush_bundles into xfrm_state GC
Fixes ABBA deadlock noticed by Patrick McHardy.
The locking in xfrm_state/xfrm_policy has always struck me as being
an overkill. A lot of the locks should be replaced by rules that
ensure the validity of most operations while a ref count is held.
Now I have an excuse to do just that :)
For 2.6.12 let's go for a simpler fix that breaks the dead lock.
__xfrm_state_delete does not need to flush the bundles immediately.
In fact, it is more efficient if we delay the flush to the GC worker
since the flush is not dependent on any particular xfrm state. By
delaying it we can do one single flush even when you're deleteing
the entire xfrm state list.

locking, we found that the pcf8574 driver does the exact contrary. It
uses a lock where it's not needed.
While we were there, we did some additional cleanups to the driver:
1* Merge pcf8574_update_client() in show_read(), as it was the only user
and the function became trivial once the locking was removed.
2* Add a validity check on values provided by user-space.
Aurelien Jarno tested the modified code for confirmation and it worked
just fine.

[PATCH] I2C: Move functionality handling from i2c-core to i2c.h
So far, the functionality handling of i2c adapters was done in i2c-core
by two exported functions: i2c_get_functionality and
i2c_check_functionality. I found that both functions could be reduced to
one line each, and propose that we turn them into inline function in the
i2c.h header file, much like other i2c helper functions (e.g.
i2c_get_clientdata, i2c_set_clientdata and i2c_clientname).
The conversion of i2c_get_functionality suppresses a legacy check which
shouldn't be needed anymore. Only one driver (s3c2410) was still relying
on it, and was fixed some days ago.
The conversion lets us get rid of two exports. Not only i2c-core gets
smaller (by 458 bytes), but the client drivers using these functions get
smaller too (typically by 48 bytes). And of course the new way is likely
to be faster too, even if it wasn't my primary objective.

[PATCH] I2C: Fix a common race condition in hardware monitoring
Grant Coady noticed that most hardware monitoring drivers are exposed to
a race condition when one writes to the sysfs files they create. While
the read calls properly request a lock on the internal data, write calls
manipulate the internal data without proper locking. This big patch
fixes that by adding locking wherever needed.
Affected drivers: adm1021, adm1025, asb100, ds1621, fscher, fscpos,
gl518sm, gl520sm, it87, lm63, lm75, lm77, lm78, lm80, lm83, lm87, lm90,
lm92, max1619, pc87360, pcf8591, sis5595, smsc47m1, via686a, w83627hf
and w83781d
The adm1026, adm1031 and lm85 were already locking on write calls, but
held the lock for code that did not require it, so they have been
modified too.
The smsc47b397 and w83l785ts drivers were not affected, because they are
read-only.
The patch should apply just fine on top of your stack, provided that you
applied all previous patches in order (in particular, there is one lm87
indentation patch which is needed).

[SELINUX]: Fix for removal of i_sock
This patch against -bk eliminates the use of i_sock by SELinux as it
appears to have been removed recently, breaking the build of SELinux in
-bk. Simply replacing the i_sock test with an S_ISSOCK test would be
unsafe in the SELinux code, as the latter will also return true for the
inodes of socket files in the filesystem, not just the actual socket
objects IIUC. Hence this patch reworks the SELinux code to avoid the
need to apply such a test in the first place, part of which was
obsoleted anyway by earlier changes to SELinux. Please apply.

This is a bad idea - we can't ever dereference those things, and we end up
with a lot of casts because arguments to and return values from OF calls
are sometimes handles and sometimes numbers.
This patch cleans things up by using u32 as the type for OF handles. The
return type of call_prom becomes int because the return value from an OF
call is often an int status code. The number of casts in prom_init.c is
reduced substantially by this patch.

[PATCH] ppc64: Fix boot memory corruption
Nathan's patch "make OF node fixup code usable at runtim" is introducing a
snaky bug. We do 2 passes over this code, one to measure how much memory
will be needed so we can allocate a single block, and one to do the actual
fixup. However, the new code does some result-checking of prom_alloc()
which breaks this mecanism, as the first pass always starts at "0", thus we
fail to measure the additional size properly and allocate a block smaller
than what we'll actually use for the fixup. This cause us to override
whatever sits there, with variable results depending on the memory layout
of the machine (but typically crashes).
This patch fixes it by starting the "measure" pass with an initial size set
to 16 and not 0.

The reservation structure is being allocated and linked to the ext3 inode at
ext3_get_block_handle(), and being freed and unlinked at the
