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show_state (which was always pretty dodgy) has been replaced by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').

This defines CONFIG_PPC_STD_MMU for ppc64, changes an instance of
sys32_ to compat_sys_ in the ppc64 syscall table, and removes a
reference to a non-existent arch/powerpc/xmon/Makefile.

This makes ppc use the syscalls.c from arch/powerpc/kernel, exports
copy_and_flush from head_32.S for use by prom_init.c (ARCH=powerpc),
and consolidates the sys_fadvise64_64 implementations for 32-bit.

It will now give ppc64 on 64bit platforms and ppc on 32bit
platforms.

At the moment we don't have a merged arch/powerpc/boot, so we build the
boot images in arch/ppc/boot and arch/ppc64/boot. Unfortunately the
makefile targets are different in those two directories, so this makes
a change to accommodate both for the moment.

The system call table has been consolidated into systbl.S. We have
separate 32-bit and 64-bit versions of entry.S and misc.S since the
code is mostly sufficiently different to be not worth merging.
There are some common bits that will be extracted in future.

This also puts a copy of indirect_pci.c in arch/powerpc/sysdev
so that we don't need to build in arch/ppc/syslib.

This doesn't change any code, just renames things so we consistently
have foo_32.c and foo_64.c where we have separate 32- and 64-bit
versions.

Merge vmlinux.lds.S.
Also remove arch/powerpc/kernel/vmlinux.lds which is a
generated file.

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.
