550a8b691c ALSA: sound/pci/asihpi: Use kzalloc
Use kzalloc rather than the combination of kmalloc and memset.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,size,flags;
statement S;
@@

-x = kmalloc(size,flags);
+x = kzalloc(size,flags);
 if (x == NULL) S
-memset(x, 0, size);
// </smpl>

b0fb75ad5c ALSA: es1688: add pedantic range checks
Smatch complains that if (dev == SNDRV_CARDS) we're one past the end of
the array.  That's unlikely to happen in real life, I suppose.

Also smatch complains about "strcpy(card->shortname, pcm->name);"
The "pcm->name" buffer is 80 characters and "card->shortname" is 32
characters.  If you follow the call paths it turns out we never actually
use more than 16 characters so it's not a problem.  But anyway, let's
make it easy for people auditing this in the future.

a20971b201 ALSA: Merge es1688 and es968 drivers
The ESS ES968 chip is nothing more then a PnP companion
for a non-PnP audio chip. It was paired with non-PnP ESS' chips:
ES688 and ES1688. The ESS' audio chips are handled by the es1688
driver in native mode. The PnP cards are handled by the ES968
driver in SB compatible mode.

Move the ES968 chip handling to the es1688 driver so the driver
can handle both PnP and non-PnP cards. The es968 is removed.

Also, a new PnP id is added for the card I acquired (the change
was tested on this card).

bfe70783ca ALSA: take tu->qlock with irqs disabled
We should disable irqs when we take the tu->qlock because it is used in
the irq handler.  The only place that doesn't is
snd_timer_user_ccallback().  Most of the time snd_timer_user_ccallback()
is called with interrupts disabled but the the first ti->ccallback()
call in snd_timer_notify1() has interrupts enabled.

This was caught by lockdep which generates the following message:

5a5e02e509 ALSA: snd-es1968: Make hardware volume buttons an input device (rev2)
The hardware volume handling code in essence just detects key presses, and
then does some hardcoded modification of the master volume based on which key
is pressed.

Clearly the right thing to do here is just report these keypresses to
userspace and let userspace decide what to with them.

This patch adds a Kconfig option which when enabled reports the volume
buttons as keypresses using an input device. When enabled this option
also gets rid of the ugly direct ac97 writes from the tasklet, the ac97lock
and the need for using a tasklet in general.

As an added bonus the keys now work identical to volume keys on a (usb)
keyboard with multimedia keys, providing visual feedback of the volume
level change, and a better range of the volume control (with a properly
configured desktop environment).

    ALSA: hda: Add powerdown for Analog Devices HDA codecs

The problem was the added resume callback that doesn't consider the
modified init hook.  The fix is simply remove the resume callback here
and make the resume normally.  This doesn't change any behavior intended
in the commit above (for shutting down the sound at suspend) but only
fixes the resume.

wacom_query_tablet_data should not be executed inside wacom_open
since wacom_open is called more than once during probe.

wacom_retrieve_hid_descriptor is removed from wacom_resume due
to the fact that the required descriptors are stored properly

8815cd030f ALSA: hda - Add position_fix quirk for Biostar mobo
The Biostar mobo seems to give a wrong DMA position, resulting in
stuttering or skipping sounds on 2.6.34.  Since the commit
7b3a177b0d, "ALSA: pcm_lib: fix "something
must be really wrong" condition", makes the position check more strictly,
the DMA position problem is revealed more clearly now.

The fix is to use only LPIB for obtaining the position, i.e. passing
position_fix=1.  This patch adds a static quirk to achieve it as default.

6c9ff1013b SELinux: Reduce max avtab size to avoid page allocation failures
Reduce MAX_AVTAB_HASH_BITS so that the avtab allocation is an order 2
allocation rather than an order 4 allocation on x86_64.  This
addresses reports of page allocation failures:

b560177f3e m68k: Fix asm constraints for atomic_sub_and_test() and atomic_add_negative()
Recently, we started seeing this on allmodconfig builds:

  CC      mm/memcontrol.o
{standard input}: Assembler messages:
{standard input}:4076: Error: operands mismatch -- statement `subl 12(%fp),170(%a0)' ignored

Correct the asm constraint, like done for m68knommu.
