Breaking lines due to some imaginary problem with a long line length is

harder to find where some error strings were printed out, because a
simple 'grep' didn't work.

The MEMGETREGIONINFO ioctl() in mtdchar.c was clobbering user memory by
overwriting more than intended, due the size of struct mtd_erase_region_info
changing in commit 0ecbc81a ('Support
for auto locking flash on power up').

Fix avoids this by copying struct members one by one with put_user(), as there
is no longer a convenient struct to use the size of as the length argument to
copy_to_user().

David Wagner added (among other things) that copy_to_user could be
probably used here.

Ingo Oeser suggested to use simple_read_from_buffer() here.

The conclusion is that proc_do_xprt doesn't check for userside buffer
size indeed so fix this by using Ingo's suggestion.

  ALSA: oxygen: fix distorted output on AK4396-based cards
  Revert "ALSA: hda - Added model selection for iMac 24""

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 a2bd7274.

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.

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.

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 abf54393 moved cmdfilter
from gendisk to request_queue. It turned out that in some subsystems
multiple gendisks share a single request_queue. So we get:

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.
