The commit 53d7d69d8ffdfa60c5b66cc2e9ee0774aaaef5c0
ALSA: hdmi - support infoframe for DisplayPort
dropped the initialization of CA field accidentally.
This resulted in only two-channel LPCM mode on Nvidia machines.

Currently the driver increments the tx_timeout counter (an error counter)
when simply resetting the part with outstanding transmit work pending.
This is an unnecessary count of an error, when all we should be doing is
just resetting the part and discarding the transmits. With this change the
only increment of tx_timeout is when the stack calls the watchdog reset
function due to a true Tx timeout.

The _TIF_WORK_MASK definition was removed in the clean up of MMU and
non-MMU arch/m68k/include/asm/thread_info*.h files (this was commit
cddafa3500fde4a07e5bf899ec97a04069f8f7ce, "merge MMU and non-MMU
thread_info.h").
It didn't get cleaned out of the entry.S code for the 68328 and 68360
based platforms. And it was replaced by a hard coded constant mask for
coldfire platforms. There is currently no need to mask any of these bits,
so fix all uses (and former uses) to check for any non-zero value.

Following symptoms were observed:
1. After raid0->raid10 takeover operation we have array with 2
missing disks.
When we add disk for rebuild, recovery process starts as expected
but it does not finish- it stops at about 90%, md126_resync process
hangs in "D" state.
2. Similar behavior is when we have mounted raid0 array and we
execute takeover to raid10. After this when we try to unmount array-
it causes process umount hangs in "D"
In scenarios above processes hang at the same function- wait_barrier
in raid10.c.
Process waits in macro "wait_event_lock_irq" until the
"!conf->barrier" condition will be true.
In scenarios above it never happens.
Reason was that at the end of level_store, after calling pers->run,
we call mddev_resume. This calls pers->quiesce(mddev, 0) with
RAID10, that calls lower_barrier.
However raise_barrier hadn't been called on that 'conf' yet,
so conf->barrier becomes negative, which is bad.
This patch introduces setting conf->barrier=1 after takeover
operation. It prevents to become barrier negative after call
lower_barrier().

md_make_request was calling bio_sectors() for part_stat_add
after it was calling the make_request function. This is
bad because the make_request function can free the bio and
because the bi_size field can change around.
The fix here was suggested by Jens Axboe. It saves the
sector count before the make_request call. I hit this
with CONFIG_DEBUG_PAGEALLOC turned on while trying to break
his pretty fusionio card.

In prepare_kernel_cred() since 2.6.29, put_cred(new) is called without
assigning new->usage when security_prepare_creds() returned an error. As a
result, memory for new and refcount for new->{user,group_info,tgcred} are
leaked because put_cred(new) won't call __put_cred() unless old->usage == 1.
Fix these leaks by assigning new->usage (and new->subscribers which was added
in 2.6.32) before calling security_prepare_creds().

In cred_alloc_blank() since 2.6.32, abort_creds(new) is called with
new->security == NULL and new->magic == 0 when security_cred_alloc_blank()
returns an error. As a result, BUG() will be triggered if SELinux is enabled
or CONFIG_DEBUG_CREDENTIALS=y.
If CONFIG_DEBUG_CREDENTIALS=y, BUG() is called from __invalid_creds() because
cred->magic == 0. Failing that, BUG() is called from selinux_cred_free()
because selinux_cred_free() is not expecting cred->security == NULL. This does
not affect smack_cred_free(), tomoyo_cred_free() or apparmor_cred_free().
Fix these bugs by
(1) Set new->magic before calling security_cred_alloc_blank().
(2) Handle null cred->security in creds_are_invalid() and selinux_cred_free().

Originally x25_parse_facilities returned
-1 for an error
0 meaning 0 length facilities
>0 the length of the facilities parsed.
5ef41308f94dc ("x25: Prevent crashing when parsing bad X.25 facilities") introduced more
error checking in x25_parse_facilities however used 0 to indicate bad parsing
a6331d6f9a429 ("memory corruption in X.25 facilities parsing") followed this further for
DTE facilities, again using 0 for bad parsing.
The meaning of 0 got confused in the callers.
If the facilities are messed up we can't determine where the data starts.
So patch makes all parsing errors return -1 and ensures callers close and don't use the skb further.

Using skb_header_cloned to check if it's safe to write to the skb is not
enough - mac80211 also touches the tailroom of the skb.
Initially this check was only used to increase a counter, however this
commit changed the code to also skip skb data reallocation if no extra
head/tailroom was needed:
commit 4cd06a344db752f513437138953af191cbe9a691
mac80211: skip unnecessary pskb_expand_head calls
It added a regression at least with iwl3945, which is fixed by this patch.

This fixes a corruption problem with the multi-block
writepages submittal change for ext4, from commit
bd2d0210cf22f2bd0cef72eb97cf94fc7d31d8cc ("ext4: use bio
layer instead of buffer layer in mpage_da_submit_io").
(Note that this corruption is not present in 2.6.37 on
ext4, because the corruption was detected after the
feature was merged in 2.6.37-rc1, and so it was turned
off by adding a non-default mount option,
mblk_io_submit. With this commit, which hopefully
fixes the last of the bugs with this feature, we'll be
able to turn on this performance feature by default in
2.6.38, and remove the mblk_io_submit option.)
The ext4 code path to bundle multiple pages for
writeback in ext4_bio_write_page() had a bug: we should
be clearing buffer head dirty flags *before* we submit
the bio, not in the completion routine.
The patch below was tested on 2.6.37 under KVM with the
postgresql script which was submitted by Jon Nelson as
documented in commit 1449032be1.
Without the patch, I'd hit the corruption problem about
50-70% of the time. With the patch, I executed the
script > 100 times with no corruption seen.
I also fixed a bug to make sure ext4_end_bio() doesn't
dereference the bio after the bio_put() call.

We reserve lowmem for the things that need it, like the ACPI
wakeup code, way early to guarantee availability. This happens
before we set up the proper pagetables, so set_memory_x() has no
effect.
Until we have a better solution, use an initcall to mark the
wakeup code executable.
