Fix synchronize_irq races with IRQ handler
As it is some callers of synchronize_irq rely on memory barriers
to provide synchronisation against the IRQ handlers. For example,
the tg3 driver does
tp->irq_sync = 1;
smp_mb();
synchronize_irq();
and then in the IRQ handler:
if (!tp->irq_sync)
netif_rx_schedule(dev, &tp->napi);
Unfortunately memory barriers only work well when they come in
pairs. Because we don't actually have memory barriers on the
IRQ path, the memory barrier before the synchronize_irq() doesn't
actually protect us.
In particular, synchronize_irq() may return followed by the
result of netif_rx_schedule being made visible.
This patch (mostly written by Linus) fixes this by using spin
locks instead of memory barries on the synchronize_irq() path.

of AT_VECTOR_SIZE_ARCH and AT_VECTOR_SIZE_BASE.
The change works for arch/powerpc, but it breaks arch/ppc because the
needed AT_VECTOR_SIZE_ARCH is not present in include/asm-ppc/system.h
and a default value of 0 is used instead. This results in
AT_VECTOR_SIZE being too small and it causes a kernel crash on loading
init.

Gabriel C reported that modprobing appletalk on current git gives a

Oops. My apologies it appears I made a mistake when creating my table
to check up on sysctl values.

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.
