Since we do not invalidate TLBs/caches on MM switches, we should not
clear the cpu_vm_mask for the CPU.

register_vpa() doesn't actually do a VPA register call it just uses the flags
you pass it, so rename it to vpa_call() to be clearer.
We can then define register_vpa() and unregister_vpa() which are both simple
wrappers around vpa_call(). (we'll need unregister_vpa() for kexec soon)
We can then cleanup vpa_init(), and because vpa_init() is only called from
platforms/pseries we remove the definition in asm-ppc64/smp.h.

There's a few places already, and soon will be more, where we synthesise
branch instructions at runtime. Rather than doing it by hand in each case,
it would make sense to have one implementation.

Oops, replacing the two u64s in struct ipc64_perm with __u32s changed
the alignment of that structure, which could mess up userspace.
Revert to using two unsigned long longs (which is what ppc32 had
originally). ppc64 orignally had two unsigned longs, but long long is
the same size on 64 bit, so this should be ok there too.

Merge include/asm-ppc/kexec.h and include/asm-ppc64/kexec.h.
The only thing that's really changed is that we now allocate crash_notes
properly on PPC32. It's address is exported via sysfs, so it's not correct
for it to be a pointer.
I've also removed some of the "we don't use this" comments, because they're
wrong (or perhaps were referring only to arch code).

This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since
cell wants them as well as pseries (and chrp can use rtas-proc.c too,

rtas_flash.c and rtas.c.

Patch from John Bowler
Fix for a compiler warning, this wasn't apparent in 2.6.12, I
believe the compiler options have been changed (somewhere) so
that passing a (void*) to a (u32) argument is now warned.
This accounts for the majority of the warnings in my builds of
the 2.6.14 kernel for NSLU2.
The patch changes pointer parameters declared as u32 to be
declared as either, for read parameters:
const volatile void __iomem *
and for write parameters:
volatile void __iomem *
