cbaed698f3 softlockup: minor cleanup, don't check task->state twice
The recent commit 16d9679f33caf7e683471647d1472bfe133d858 changed
check_hung_task() to filter out the TASK_KILLABLE tasks. We can
move this check to the caller which has to test t->state anyway.

011fec7486 Un-break printk strings in x86 PCI probing code
Breaking lines due to some imaginary problem with a long line length is
often stupid and wrong, but never more so when it splits a string that
is printed out into multiple lines.  This really ended up making it much
harder to find where some error strings were printed out, because a
simple 'grep' didn't work.

I'm sure there is tons more of this particular idiocy hiding in other
places, but this particular case hit me once more last week. So fix it.

ddef43a843 block: restore original behavior of /proc/partition when there's no partition
/proc/partitions didn't use to write out the header if there was no
partition.  However, recent commit 66c64afe changed the behavior.
This is nothing major but there's no reason to change user visible
behavior without a good rationale.  Restore the original behavior.

Note that 2.6.28 has clean up changes scheduled which will replace
this rather hacky implementation.

316d9679f3 Don't trigger softlockup detector on network fs blocked tasks
Pulling the ethernet cable on a 2.6.27-rc system with NFS mounts
currently leads to an ongoing flood of soft lockup detector backtraces
for all tasks blocked on the NFS mounts when the hickup takes
longer than 120s.

I don't think NFS problems should be all that noisy.

Luckily there's a reasonably easy way to distingush this case.

Don't report task softlockup warnings for tasks in TASK_KILLABLE
state, which is used by the network file systems.

I believe this patch is a 2.6.27 candidate.

This reverts commit a2bd7274b4.

It wasn't really right to begin with (there's a better fix for the
problem with e820 reservations clashing with PCI BAR's pending), but it
also actually causes more regressions, so it should be reverted even
before the better fix is finalized.

Rafael reports that this commit broke AHCI detection, and thus causes
the kernel to not boot on his quad core test box.

df91bc23dc ALSA: oxygen: fix distorted output on AK4396-based cards
When changing the sample rate, the CMI8788's master clock output becomes
unstable for a short time.  The AK4396 needs the master clock to do SPI
writes, so writing to an AK4396 control register directly after a sample
rate change will garble the value.  In our case, this leads to the DACs
being misconfigured to I2S sample format, which results in a wrong
output level and horrible distortions on samples louder than -6 dB.

To fix this, we need to wait until the new master clock signal has
become stable before doing SPI writes.

bb23b431db remove blk_register_filter and blk_unregister_filter in gendisk
This patch remove blk_register_filter and blk_unregister_filter in
gendisk, and adds them to sd.c, sr.c. and ide-cd.c

The commit abf5439370 moved cmdfilter
from gendisk to request_queue. It turned out that in some subsystems
multiple gendisks share a single request_queue. So we get:

In the long term, we need to fix such subsystems but we need a quick
fix now. This patch add the command filter support to only sd and sr
though it might be useful for other SG_IO users (such as cciss).

e3c71a3291 sparc: Fix resource flags for PCI children in OF device tree.
When a device is under an EBUS or ISA bus, the resource flags
don't get set properly.

Fix this by re-evaluating the resource flags at each level of
bus as we apply ranges on the way to the root.  And let PCI
override any existing flags setting, but don't let the
default flags calculator make such overrides.

838726c475 cifs: fix O_APPEND on directio mounts
The direct I/O write codepath for CIFS is done through
cifs_user_write(). That function does not currently call
generic_write_checks() so the file position isn't being properly set
when the file is opened with O_APPEND.  It's also not doing the other
"normal" checks that should be done for a write call.

The problem is currently that when you open a file with O_APPEND on a
mount with the directio mount option, the file position is set to the
beginning of the file. This makes any subsequent writes clobber the data
in the file starting at the beginning.

This seems to fix the problem in cursory testing. It is, however
important to note that NFS disallows the combination of
(O_DIRECT|O_APPEND). If my understanding is correct, the concern is
races with multiple clients appending to a file clobbering each others'
data. Since the write model for CIFS and NFS is pretty similar in this
regard, CIFS is probably subject to the same sort of races. What's
unclear to me is why this is a particular problem with O_DIRECT and not
with buffered writes...

Regardless, disallowing O_APPEND on an entire mount is probably not
reasonable, so we'll probably just have to deal with it and reevaluate
this flag combination when we get proper support for O_DIRECT. In the
meantime this patch at least fixes the existing problem.

f3ade83780 sched: fix sched_rt_rq_enqueue() resched idle
When sysctl_sched_rt_runtime is set to something other than -1 and the
CONFIG_RT_GROUP_SCHED kernel parameter is NOT enabled, we get into a state
where we see one or more CPUs idling forvever even though there are
real-time
tasks in their rt runqueue that are able to run (no longer throttled).

The sequence is:

- A real-time task is running when the timer sets the rt runqueue
    to throttled, and the rt task is resched_task()ed and switched
    out, and idle is switched in since there are no non-rt tasks to
    run on that cpu.

- Eventually the do_sched_rt_period_timer() runs and un-throttles
    the rt runqueue, but we just exit the timer interrupt and go back
    to executing the idle task in the idle loop forever.

If we change the sched_rt_rq_enqueue() routine to use some of the code
from the CONFIG_RT_GROUP_SCHED enabled version of this same routine and
resched_task() the currently executing task (idle in our case) if it is
a lower priority task than the higher rt task in the now un-throttled
runqueue, the problem is no longer observed.

d97240552c sctp: fix random memory dereference with SCTP_HMAC_IDENT option.
The number of identifiers needs to be checked against the option
length.  Also, the identifier index provided needs to be verified
to make sure that it doesn't exceed the bounds of the array.

328fc47ea0 sctp: correct bounds check in sctp_setsockopt_auth_key
The bonds check to prevent buffer overlflow was not exactly
right.  It still allowed overflow of up to 8 bytes which is
sizeof(struct sctp_authkey).

Since optlen is already checked against the size of that struct,
we are guaranteed not to cause interger overflow either.

4c246edd25 IB/mlx4: Actually return L_Key and R_Key for fast register MRs
Initialize the L_Key and R_Key for memory regions returned from
mlx4_ib_alloc_fast_reg_mr().  Otherwise callers just get garbage for
the memory keys and can't do anything useful with these MRs.

a152db71d9 tty: Fix termios tty window resize race with pty/tty pair
Kanru Chen posted a patch versus the old code which deals with the case
where you resize the pty side of a pty/tty pair. In that situation the
termios data is updated for both pty and tty but the locks are not held
for the right side.

This implements the fix differently against the updated tty code. Patch
by self but the hard bit (noticing and fixing the bug) is thanks to Kanru
Chen.

f753f3272b tty: TIOCGSOFTCAR/SSOFTCAR on pty is wron
The termios settings ioctls on a pty should affect the bound tty side not
the pty. The SOFTCAR ioctls use the wrong device file.
