Commit a65e7bfcd74e4c0939f235d2bf9f48ddb3a57991 broke the UML build with
the following error -
In file included from fs/proc/kcore.c:17:
include/linux/elfcore.h: In function 'elf_core_copy_task_regs':
include/linux/elfcore.h:129: error: implicit declaration of function 'task_pt_regs'
Fix this by restoring the previous behavior of returning 0 for all arches
like UML that don't define task_pt_regs.

There is a regression, introduced in aa202455eec51699e44f658530728162cefa1307
(in alsa-kernel) which I noticed when trying to use the headphone socket on
my EeeCPC 901: the output was *very* quiet, practically silent.
This patch corrects the control types to that which was obviously intended in
the referenced commit.

This patch adds kmemleak_alloc/free callbacks to the bootmem allocator.
This would allow scanning of such blocks and help avoiding a whole class
of false positives and more kmemleak annotations.

Functions like free_bootmem() are allowed to free only part of a memory
block. This patch adds support for this via the kmemleak_free_part()
callback which removes the original object and creates one or two
additional objects as a result of the memory block split.

The kmalloc_large() and kmalloc_large_node() functions were missed when
adding the kmemleak hooks to the slub allocator. However, they should be
traced to avoid false positives.

Many of the false positives in kmemleak happen on busy systems where
objects are allocated during a kmemleak scanning episode. These objects
aren't scanned by default until the next memory scan. When such object
is added, for example, at the head of a list, it is possible that all
the other objects in the list become unreferenced until the next scan.
This patch adds checking for newly allocated objects at the end of the
scan and repeats the scanning on these objects. If Linux allocates
new objects at a higher rate than their scanning, it stops after a
predefined number of passes.

Initially, the scan_mutex was acquired in kmemleak_open() and released
in kmemleak_release() (corresponding to /sys/kernel/debug/kmemleak
operations). This was causing some lockdep reports when the file was
closed from a different task than the one opening it. This patch moves
the scan_mutex acquiring in kmemleak_write() or kmemleak_seq_start()
with releasing in kmemleak_seq_stop().

Since the leaks are no longer printed to the syslog, there is no point
in keeping this limitation. All the suspected leaks are shown on

Patch 08687aec71bc9134fe336e561f6did877bacf74fc0a (x86: unify
power/cpu_(32|64).c) renamed cpu_32.c to cpu.c, but did not update
the special compilation flags for the file for the new name.
This patch fixes the compilation flags, and therefore fixes resume

HDA driver disabled HD audio 64bit address support for all AMD
SB600/SB700/SB800 platforms with commit
09240cf429505891d6123ce14a29f58f2a60121e due to one SB600 issue
reported by community, but we do not see the similar issue on
SB700/SB800 platforms.

Serio ports are not being restarted any longer because resume operations
after hibernate do nothing, since the device has not been marked as
suspended. This happens because suspend is only considering the SUSPEND
event but not the FREEZE event.
Note that this driver has still to migrate to dev_pm_ops, but this fixes
this particular bug now.

Current implementation of spin_event_timeout can be interrupted by an
IRQ or context switch after testing the condition, but before checking
the timeout. This can cause the loop to report a timeout when the
condition actually became true in the middle.
This patch adds one final check of the condition upon exit of the loop
if the last test of the condition was still false.

However on G4X platform we need to probe possible

then fetch our desired EDID, i.e on DG45ID platform
we successfully fetch EDID by GPIOD port.

When we reclaim the tx desc, we always assume that the
last desc is a holding desc, which is not true, and skip it.
If the tx queue is drained during channel change, internal
reset and etc, the last descriptor may not be the holding
descriptor and we fail to reclaim them. This results in the
following two issues.
1. Tx stuck - We drop all the frames coming from upper layer
due to shortage in tx desc.
2. Crash - If we fail to reclaim a tx descriptor, we miss to
update the tx BA window with the seq number of the frame
associated to that desc, which, at some point, result in
the following crash due to an assert failure in ath_tx_addto_baw().
This patch fixes these two issues.

Fix condition in which radio LED did not initialize correctly, and remove
4 compilation warnings.
After the recent changes in rfkill, the radio LED used by b43/b43legacy
did not always initialize correctly.
Both b43 and b43legacy used the deprecated variable radio_enabled in
struct ieee80211_conf.

The fixed widget NIDs in patch_via.c seem wrong for some codecs,
and it resulted in the invalid capture source selection.
This patch adds the code to parse the topology instead of using
fixed numbers in order to get the right MUX widget id corresponding
to the ADCs.

The following test script triggers a deadlock on ext2 filesystem:
while true; do quotaon /dev/hda >&/dev/null; usleep $RANDOM; done &
while true; do quotaoff /dev/hda >&/dev/null; usleep $RANDOM; done &
I found there is a potential deadlock between quotaon and quotaoff (or
quotasync). Basically, all of quotactl operations need to be protected by
dqonoff_mutex. vfs_quota_off and vfs_quota_sync also call sb->s_op->quota_write
that needs to grab the i_mutex of the quota file. But in vfs_quota_on_inode
(called from quotaon operation), the current code tries to grab the i_mutex of
the quota file first before getting quonoff_mutex.
Reverse the order in which we take locks in vfs_quota_on_inode().
Jan Kara: Changed changelog to be more readable, made lockdep happy with
I_MUTEX_QUOTA.

Performance counters need 64 bit atomic operations.
To keep the patch small we use the simple generic atomic64_t implementation.
The native implementation follows with the next kernel.
