7cc955c8fd [POWERPC] virtex bug fix: Use canonical value for AC97 interrupt xparams
The ml300 and ml403 xparameters.h files use different macros for the
AC97 interrupt pin assignments.  This normalizes them to a canonical
value similar to what EDK generates for most other devices.  This is
needed to get ml300 support to compile in arch/ppc.

150030b78a NFS: Switch from intr mount option to TASK_KILLABLE
By using the TASK_KILLABLE infrastructure, we can get rid of the 'intr'
mount option.  We have to use _killable everywhere instead of _interruptible
as we get rid of rpc_clnt_sigmask/sigunmask.

84f4506cb7 [PARISC] lba_pci: pci_claim_resources disabled expansion roms
radeonfb was HPMC-ing my C8000 by trying to map its expansion rom from
IO_VIEW, instead of PA_VIEW. Fix seems to be to ensure that its disabled
ROM is properly inserted into the resource tree.

FIXME: this will result in a whinging printk for cards which share expansion
ROMS, such as a quad tulip. Thankfully, it isn't harmful.

00a5825332 Fix oprofile configuration breakage
The cleanup 09cadedbdc broke the oprofile
configuration for MIPS by allowing oprofile support to be built for
kernel models where oprofile doesn't have a chance in hell to work.

Just a dependecy list on a number of architectures is - surprise - broken
and should as per past discussions probably in most considered to be
broken in most cases.  So I introduce a dependency for the oprofile
configuration on ARCH_SUPPORTS_OPROFILE.

2421ba5b57 [PARISC] timer interrupt should not be IRQ_DISABLED
The timer interrupt had accidentally been marked IRQ_DISABLED since
IRQ_PER_CPU had been OR-ed in, instead of set. This had been working
by accident for quite a while.

Commit c642b8391c changed the behaviour of
IRQ_PER_CPU interrupts, which previously weren't checked for IRQ_DISABLED.

81a3843f97 [POWERPC] Fix hardware IRQ time accounting problem.
The commit fa13a5a1f2 (sched: restore
deterministic CPU accounting on powerpc), unconditionally calls
update_process_tick() in system context.  In the deterministic
accounting case this is the correct thing to do.  However, in the
non-deterministic accounting case we need to not do this, since doing
this results in the time accounted as hardware irq time being
artificially elevated.

Also this collapses 2 consecutive '#ifdef CONFIG_VIRT_CPU_ACCOUNTING'
checks in time.h into one for neatness.
