We really need to check TIF_RESTORE_SIGMASK before returning to
userspace. The existing code does not necessarily do this.
Define the work masks as a bitwise OR of the respective flags instead
of a hardcoded hex value to make it easier to spot errors like this in
the future.

get_cpu() always returns zero on non-SMP builds, but we
really want the physical cpu number in this code in order
to do the right thing.

During accept/migrate the code attempts to copy the addresses from
the parent endpoint to the new endpoint. However, if the parent
was bound to a wildcard address, then we end up pointlessly copying
all of the current addresses on the system.

IPv4 stack doesn't reply any ICMP destination unreachable message

* 'merge' of master.kernel.org:/pub/scm/linux/kernel/git/paulus/powerpc:
[POWERPC] virtex bug fix: Use canonical value for AC97 interrupt xparams
[POWERPC] Update defconfigs
[POWERPC] PS3: Update ps3_defconfig
[POWERPC] Update iseries_defconfig
[POWERPC] Fix hardware IRQ time accounting problem.

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.

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.

The cleanup 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 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.

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 c642b8391cf8efc3622cc97329a0f46e7cbb70b8 changed the behaviour of
IRQ_PER_CPU interrupts, which previously weren't checked for IRQ_DISABLED.

The commit fa13a5a1f25f671d084d8884be96fc48d9b68275 (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.

directory
The bootwrapper script currently generates an 'otheros.bld' file in
addition to the file specified by the -o option, when asked to build a
wrapper for PS3.
It should do that in the same directory as the output, not the directory
where the wrapper objects are kept (which might potentially not be
writable when the script runs).
Arguably, the 'otheros.bld' ought to be created with the filename
specified as the -o argument. But that's a more intrusive change.
