4a89a04f1e [PATCH] alpha smp fix (part #2)
This fixes the bug that caused BUG_ON(!irqs_disabled()) to trigger in
run_posix_cpu_timers() on alpha/smp.  We didn't disable interrupts
properly before calling smp_percpu_timer_interrupt().

We *do* disable interrupts everywhere except this unfortunate
smp_percpu_timer_interrupt().  Fixed thus.

db57955476 [PATCH] ARM: replace schedule_timeout() with msleep()
Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. Neither signals nor wait-queue events are
important at this point in the code, I believe.

Patch from Ben Dooks

The omnimeter_defconfig does not define any machines and

Patch from Todd Poynor

eaf05be039 [PATCH] alpha smp fix
As usual, the reason of this breakage is quite silly: in do_entIF, we
are checking for PS == 0 to see whether it was a kernel BUG() or
userspace trap.

It works, unless BUG() happens in interrupt - PS is not 0 in kernel mode
due to non-zero IPL, and the things get messed up horribly then.  In
this particular case it was BUG_ON(!irqs_disabled()) triggered in
run_posix_cpu_timers(), so we ended up shooting "current" with the
bursts of one SIGTRAP and three SIGILLs on every timer tick.  ;-)

The new EABI gcc adds -mthumb-interwork by default, even if

if the option is supported. This is also useful since we don't need

719d1cd867 [PATCH] ppc64: Replace custom locking code with a spinlock
The hvlpevent_queue (formally ItLpQueue) has a member called xInUseWord
which is used for serialising access to the queue. Because it's a word
(ie. 32 bit) there's a custom 32-bit version of test_and_set_bit() or
thereabouts in ItLpQueue.c.

The xInUseWord is not shared with they hypervisor, so we can replace it
with a spinlock and remove the custom code.

There is also another locking mechanism (ItLpQueueInProcess). This is
redundant because it's only manipulated while the lock's held. Remove it.

bea248fb30 [PATCH] ppc64: Remove lpqueue pointer from the paca on iSeries
The iSeries code keeps a pointer to the ItLpQueue in its paca struct. But
all these pointers end up pointing to the one place, ie. xItLpQueue.

So remove the pointer from the paca struct and just refer to xItLpQueue
directly where needed.

The only complication is that the spread_lpevents logic was implemented by
having a NULL lpqueue pointer in the paca on CPUs that weren't supposed to
process events. Instead we just compare the spread_lpevents value to the
processor id to get the same behaviour.
