The merged version follows the ppc64 version pretty closely mostly,
and in fact ARCH=ppc64 now uses the arch/powerpc/xmon version.
The main difference for ppc64 is that the 'p' command to call
show_state (which was always pretty dodgy) has been replaced by
the ppc32 'p' command, which calls a given procedure (so in fact
the old 'p' command behaviour can be achieved with 'p $show_state').

The sc instruction emulation can't be done the same way on 32-bit
as 64-bit yet, but this should work OK.

Somewhere along the line we got two definitions of set_tb(). They look to
be identical although they're not textually identical. So remove the #ifdef
CONFIG_PPC64 version, leaving the common version in time.h.

This fixes up a variety of minor problems in compiling with ARCH=ppc
arising from using the merged versions of various header files.
A lot of the changes are just adding #include <asm/machdep.h> to
files that use ppc_md or smp_ops_t.
This also arranges for us to use semaphore.c, vecemu.c, vector.S and
fpu.S from arch/powerpc/kernel when compiling with ARCH=ppc.

This adds register definitions from the ppc64 processor.h to reg.h,
and makes a single merged processor.h. I moved __is_processor from
the ppc64 system.h to the merged reg.h along with the PVR register
constants.

Complete moving arch/ppc64/kernel/mpic.h,
include/asm-ppc/reg.h, include/asm-ppc64/kdebug.h
and include/asm-ppc64/kprobes.h
Add arch/powerpc/platforms/Makefile and use it from
arch/powerpc/Makefile
Introduce OLDARCH temporarily so we can point back to
the originating architecture

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.
