[ALSA] add sigmatel codec support
HDA generic driver,HDA Codec driver
Add initial SigmaTel codec support for 9200 and 922x. Note that
this hda patch relies on the configuration default registers to
be set correctly (normally by BIOS/firmware) in order for it to
set up pin widgets properly. There's a test switch in the patch
so it will work with the SigmaTel reference boards that are usually
plugged into a system that doesn't set the configuration default
registers. It supports 2 channel analog out and line/mic in. I
plan to add >2 channel support and spdif support shortly.
Please apply.

AC97 Codec
The handling of shared surround/clfe output jacks with line/mic-in
on some AC97 codecs is improved.
Instead of 'Line-In As Surround' or 'Mic As Center/LFE' switch, two
new enum controls are introduced: 'Channel Mode' and 'Surround Jack Mode'.
The formar changes the current output mode among 2, 4 and 6-channels.
The latter controls whether the jacks are shared or independent.
[ALSA] Support all sample rate conversion capabilities of DXS channels
Documentation,VIA82xx driver
Add support for full sample rate conversion capabilities of DXS
channels present in VIA VT8233/5/7 controllers:
- any sample rate in the 8000 ... 48000 Hz range is supported even if
the AC'97 codec supports only 48000 Hz output;
- different DXS channels can use different sample rates at the same
time (the controller performs required sample rate conversion and
mixing in hardware).
[ALSA] Improve SPDIF playback via the P16V/CA0151 chip.
EMU10K1/EMU10K2 driver
Although we can set 44100 as the output rate, the SPDIF can do it, but the Analog output cannot.
The SPDIF has the bug, whereby the Left channel arrives one sample late, so although we don't do any resampling,
it is not good for AC3 non-audio output.

HDA Codec driver
Patch by C.L. Tien <cltien@cmedia.com.tw>:
The patch makes cm9880 to choose multi-channel jacks automatically.
1. I found the current code has basic_init, which already includes
necessary controls for 6-stack initialization, so I don't need
another model.
2. I add a new model 'auto' to let the driver find a. if there are
option real panel/front panel, b. the jacks to be used for multichannel.
Because the jack color are based on MS's channel sequence, so the 'auto'
model will pick the same jacks for multichannel MS uses. I did this to
hope to minimize users questions. These code can also be applied to other
codecs but I don't have any to test.

[PATCH] cpuset exit NULL dereference fix
There is a race in the kernel cpuset code, between the code
to handle notify_on_release, and the code to remove a cpuset.
The notify_on_release code can end up trying to access a
cpuset that has been removed. In the most common case, this
causes a NULL pointer dereference from the routine cpuset_path.
However all manner of bad things are possible, in theory at least.
The existing code decrements the cpuset use count, and if the
count goes to zero, processes the notify_on_release request,
if appropriate. However, once the count goes to zero, unless we
are holding the global cpuset_sem semaphore, there is nothing to
stop another task from immediately removing the cpuset entirely,
and recycling its memory.
The obvious fix would be to always hold the cpuset_sem
semaphore while decrementing the use count and dealing with
notify_on_release. However we don't want to force a global
semaphore into the mainline task exit path, as that might create
a scaling problem.
The actual fix is almost as easy - since this is only an issue
for cpusets using notify_on_release, which the top level big
cpusets don't normally need to use, only take the cpuset_sem
for cpusets using notify_on_release.
This code has been run for hours without a hiccup, while running
a cpuset create/destroy stress test that could crash the existing
kernel in seconds. This patch applies to the current -linus
git kernel.

The original pwc author raised some questions about the reverse
engineering of the decompressor algorithms used in the pwc driver.
Having done some detailed investigation it appears those concerns that
clean room policy was not followed are reasonable. I've also had a
friendly discussion with Philips to ask their view on this.
This removes the problem items of code which reduces the pwc
functionality in the kernel a little but leaves all the framework for
setup that will be needed for decompressors in user space (where they
eventually belong). This change set is designed to be the minimal risk
change set given that 2.6.12 is hopefully close to hand, with a view to
merging the much updated pwc code in 2.6.13 series kernels.
Someone else can then redo the decompressors properly (clean room) in
user space.
Note that while its easy to say that it should have been caught earlier,
but the violation was really only obvious to someone who had access to
both the proprietary source and the 'GPL' source.

But it's not regparm functions that need not to make tail calls, it's
asmlinkage functions called with a user pt_regs frame on the stack

[PKT_SCHED] netem: use only inner qdisc -- no private skbuff queue
Netem works better if there if packets are just queued in the inner discipline
rather than having a separate delayed queue. Change to use the dequeue/requeue
to peek like TBF does.
By doing this potential qlen problems with the old method are avoided. The problems
happened when the netem_run that moved packets from the inner discipline to the nested
discipline failed (because inner queue was full). This happened in dequeue, so the
effective qlen of the netem would be decreased (because of the drop), but there was
no way to keep the outer qdisc (caller of netem dequeue) in sync.
The problem window is still there since this patch doesn't address the issue of
requeue failing in netem_dequeue, but that shouldn't happen since the sequence dequeue/requeue
should always work. Long term correct fix is to implement qdisc->peek in all the qdisc's
to allow for this (needed by several other qdisc's as well).

CD/DVD is inserted into the tray when the system is booted and if
before the OS bootup the BIOS checked for the presence of a bootable
CD/DVD into the drive, during the IDE probe phase the drive may
result busy and remain so for the next 25/30 seconds . This cause the
drive to be skipped during the booting phase and not begin usable
until the next reboot (if the reboot goes well and the drive doesn't
timeout again).
Solution: Rising the timeout time from 10 seconds to 35 seconds
(during these 35 seconds every drive should wake up for sure
according to the tests I've done).

[PATCH] libata: Fix zero sg_dma_len() on 64-bit platform
When testing ATAPI PIO data transfer on the ppc64 platform, __atapi_pio_bytes() got zero when
sg_dma_len() is used. I checked the <asm-ppc64/scatterlish.h>, the struct scatterlist is defined as:
struct scatterlist {
struct page *page;
unsigned int offset;
unsigned int length;
/* For TCE support */
u32 dma_address;
u32 dma_length;
};
So, if the scatterlist is not DMA mapped, sg_dma_len() will return zero on ppc64.
The same problem should occur on the x86-64 platform.
On the i386 platform, sg_dma_len() returns sg->length, that's why the problem does not occur on an i386.
Changes:
- Use sg->length if the scatterlist is not DMA mapped (yet).
