This creates the directory structure under arch/powerpc and a bunch
of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.

For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
to files in those directories and files outside arch/powerpc.

The boot directory is still not merged.  That's going to be interesting.

powerpc: Merge semaphore.h

Adopted the ppc64 version of semaphore.h.  The 32-bit version used
smp_wmb(), but recent updates to atomic.h mean this is no longer required.
The 64-bit version made use of unlikely(), which has been retained in the
combined version.

This patch requires the recent atomic.h patch.

Merge asm-ppc*/rwsem.h into include/asm-powerpc.
Removed smp_*mb() memory barriers from the ppc32 code
as they are now burried in the atomic_*() functions as
suggested by Paul, implemented by Arnd, and pushed out
by Becky.  I am not the droid you are looking for.

This patch depends on Becky's atomic.h merge patch.

The spinlock_types.h merge renamed the structure for raw_spinlock_t to

be updated to match.  Apparently, this seems to only be caught when

As davem points out, this wasn't such a great idea.  There may be some code
which does:

	size = 1024*1024;
	while (kmalloc(size, ...) == 0)
		size /= 2;

which will now explode.

Current kernel has a couple of sneaky bugs in the ppc64 hugetlb code that
cause huge pages to be potentially left stale in the hash table and TLBs
(improperly invalidated), with all the nasty consequences that can have.

One is that we forgot to set the "secondary" bit in the hash PTEs when
hashing a huge page in the secondary bucket (fortunately very rare).

The other one is on non-LPAR machines (like Apple G5s), flush_hash_range()
which is used to flush a batch of PTEs simply did not work for huge pages.
Historically, our huge page code didn't batch, but this was changed without
fixing this routine.  This patch fixes both.
