[ALSA] hda-codec - Fix conflict of Master volume in STAC92xx codec
The addition of volume knob as Master volume resulted in conflict with

This patch fixes the conflict, and still keeps the Master control for
codecs without volume knob as much as possible.

[ALSA] snd-bt87x: Make the load_all option work correctly
If the load_all option was turned on all cards would be treated as unknown,
even those which are in the database. Of course, if the card is in the
database there is no reason to use the load_all option. It's there to force
loading when the card isn't in the database. But there are out of date wikis
that say to do this and some distros might turn this option on by default.
So, we keep the load_all option from turning known cards into unknown cards.

[ALSA] protect Dreamcast PCM driver (AICA) from G2 bus effects
The G2 bus on the SEGA Dreamcast connects both the maple peripheral
bus and the AICA sound memory. DMA requests on one can cause the other
to timeout on memory operations.
This patch prevents maple interrupts from causing hiccoughs in the
AICA sound (maple bus code will land in 2.6.24).
There are other cleanups for this (AICA) code - but this is in effect

These helper routines supply most of the virtqueue_ops for hypervisors

2) They have an unfortunate limit of 65535 bytes per sg element.

This has two main effects:
1) When Jes's patch changes the hypercall args to be a generic "struct

arch code, so if it has to copy args or something it can do so, and

ARM: OMAP: fix default sys_ck.rate for boot-time DPLL detection
In the clock init code, the DPLL value set by the bootloader is
queried, but always turns zero due it's parent clock (sys_ck) having
no default rate. This results in the improper setting of the default
PRCM rate-table entry and any queries of virt_prcm_set rate to return 0.
Rather than setting a static sys_ck.rate, detect the correct value at
boot time.

SELinux: always check SIGCHLD in selinux_task_wait
When checking if we can wait on a child we were looking at
p->exit_signal and trying to make the decision based on if the signal
would eventually be allowed. One big flaw is that p->exit_signal is -1
for NPTL threads and so aignal_to_av was not actually checking SIGCHLD
which is what would have been sent. Even is exit_signal was set to
something strange it wouldn't change the fact that the child was there
and needed to be waited on. This patch just assumes wait is based on
SIGCHLD. Specific permission checks are made when the child actually
attempts to send a signal.
This resolves the problem of things like using GDB on confined domains
such as in RH BZ 232371. The confined domain did not have permission to
send a generic signal (exit_signal == -1) back to the unconfined GDB.
With this patch the GDB wait works and since the actual signal sent is
allowed everything functions as it should.

[MIPS] time: SMP-proofing of Sibyte clockevent/clocksource code.
The BCM148 has 4 cores but there are also just 4 generic timers available
so use the ZBbus cycle counter instead of it. In addition the ZBbus
counter also offers a much higher resolution and 64-bit counting so I'm
considering a later complete conversion to it once I figure out if all
members of the Sibyte SOC family support it - the docs seem to agree but
the headers files seem to disagree ...

Change table chaining layout
Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:
- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
NULL when passed such an entry.
It's thus important that sg table users use the proper accessors to get
and set the page member.

kbuild: fix modules_install after a 'make vmlinux'
make vmlinux would delete the content of $(MODVERDIR)
equals .tmp_versions. This caused a subsequent
make modules_install to fail.
Fix it so we clean the directory only for the
modules build - but we still unconditionally create it so
we can do:
make dir/file.ko
without a preceeding make modules.

Update documentation to the current state of affairs. Remove duplicated
method descruptions in exportfs.h and point to Documentation/filesystems/
Exporting instead. Add a little file header comment in expfs.c describing
what's going on and mentioning Neils and my copyright [1].
