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.

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.

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'.

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.

Jan's crosscompile page [1] shows, that one regression in 2.6.15-rc is
that the v850 defconfig does no longer compile.
The compile error is:

In file included from /usr/src/ctest/rc/kernel/arch/v850/kernel/setup.c:17:

make[2]: *** [arch/v850/kernel/setup.o] Error 1

The #include <asm/smp.h> in irq.h was intruduced in 2.6.15-rc.
Since include/linux/irq.h needs code from asm/smp.h only in the
CONFIG_SMP=y case and linux/smp.h #include's asm/smp.h only in the
CONFIG_SMP=y case, I'm suggesting this patch to #include <linux/smp.h>
in irq.h.
I've tested the compilation with both CONFIG_SMP=y and CONFIG_SMP=n
on i386.

There's currently a diagnostic printk in relay_switch_subbuf() meant as
a warning if you accidentally try to log an event larger than the
sub-buffer size.
The problem is if this happens while logging from somewhere it's not
safe to be doing printks, such as in the scheduler, you can end up with
a deadlock. This patch removes the warning from relay_switch_subbuf()
and instead prints some diagnostic info when the channel is closed.

Tested on 2.6.14.4 with "ip monitor addr" and with the program

The udelay() inline for ia64 uses the ITC. If CONFIG_PREEMPT is enabled
and the platform has unsynchronized ITCs and the calling task migrates
to another CPU while doing the udelay loop, then the effective delay may
be too short or very, very long.
This patch disables preemption around 100 usec chunks of the overall
desired udelay time. This minimizes preemption-holdoffs.
udelay() is now too big to be inline, move it out of line and export it.

In the scenario that a link was broken, the devloss timer for each
rport was expire at roughly the same time, causing lots of "delete"
workqueue items being queued. Depth is dependent upon the number of
rports that were on the link.
The rport target remove calls were calling flush_scheduled_work(),
which would interrupt the stream, and start the next workqueue item,
which did the same thing, and so on until recursion depth was large.
This fix stops the recursion in the initial delete path, and pushes it
off to a host-level work item that reaps the dead rports.

Other hardware supports ATAPI, but the driver does something nasty such
as calling BUG() when an ATAPI command is issued.
