Modules: ALSA Core
Backward-compatibility typedefs are stored in the new header, typedefs.h,
for out-of-tree drivers. This will be removed in future.

Modules: AC97 Codec
Remove the definition of ac97_enum struct from the public ac97_codec.h.
It's used only in the module.
The location of struct ac97_pcm is moved closer to its accessor
to improve readability.

Add support for the CS5535 Audio device. I've fixed up some errors as per
Takashi's advice from the thread:

In commit 3D59121003721a8fad11ee72e646fd9d3076b5679c, the x86 and x86-64
<asm/param.h> was changed to include <linux/config.h> for the
configurable timer frequency.
However, asm/param.h is sometimes used in userland (it is included
indirectly from <sys/param.h>), so your commit pollutes the userland
namespace with tons of CONFIG_FOO macros. This greatly confuses
software packages (such as BusyBox) which use CONFIG_FOO macros
themselves to control the inclusion of optional features.
After a short exchange, Christoph approved this patch

The below "jumbo" patch fixes the following problems in MLDv2.
1) Add necessary "ntohs" to recent "pskb_may_pull" check [breaks
all nonzero source queries on little-endian (!)]
2) Add locking to source filter list [resend of prior patch]
3) fix "mld_marksources()" to
a) send nothing when all queried sources are excluded
b) send full exclude report when source queried sources are
not excluded
c) don't schedule a timer when there's nothing to report
NOTE: RFC 3810 specifies the source list should be saved and each
source reported individually as an IS_IN. This is an obvious DOS
path, requiring the host to store and then multicast as many sources
as are queried (e.g., millions...). This alternative sends a full,
relevant report that's limited to number of sources present on the
machine.
4) fix "add_grec()" to send empty-source records when it should
The original check doesn't account for a non-empty source
list with all sources inactive; the new code keeps that
short-circuit case, and also generates the group header
with an empty list if needed.
5) fix mca_crcount decrement to be after add_grec(), which needs
its original value
These issues (other than item #1 ;-) ) were all found by Yan Zheng,
much thanks!

Fix n_r3964 timeouts (hardcoded for 100Hz)
Also the include of <asm/termios.h> in 'n_r3964.h' is unnecessary and
prevents using the header file in any application that has to include
<termios.h> due to duplicate definition of 'struct termio'.

Based on __build_read_lock_const, this looked like a bug.
[ Indeed. Maybe nobody uses this version? Worth fixing up anyway ]

Fixes a compiler error in node_to_first_cpu, __ffs expects unsigned long as
a parameter; instead cpumask_t was being passed. The macro
node_to_first_cpu was not yet used in x86_64 and ia64 arches, and so we never
hit this. This patch replaces __ffs with first_cpu macro, similar to other
arches.

Currently a simple
void foo(void) { preempt_enable(); }
produces the following code on ARM:
foo:
bic r3, sp, #8128
bic r3, r3, #63
ldr r2, [r3, #4]
ldr r1, [r3, #0]
sub r2, r2, #1
tst r1, #4
str r2, [r3, #4]
blne preempt_schedule
mov pc, lr
The problem is that the TIF_NEED_RESCHED flag is loaded _before_ the
preemption count is stored back, hence any interrupt coming within that
3 instruction window causing TIF_NEED_RESCHED to be set won't be
seen and scheduling won't happen as it should.
Nothing currently prevents gcc from performing that reordering. There
is already a barrier() before the decrement of the preemption count, but
another one is needed between this and the TIF_NEED_RESCHED flag test
for proper code ordering.
