APUS (the Amiga Power-Up System) is not supported under arch/powerpc
and it's unlikely it ever will be. Therefore, this patch removes the
fragments of APUS support code from arch/powerpc which have been
copied from arch/ppc.
A few APUS references are left in asm-powerpc in .h files which are
still used from arch/ppc.

Commit d1953c8888ef034b912ee33bc2ea2cce6a414402 removed the use of
4level-fixup.h for 32-bit systems under arch/powerpc. However, I
missed a few things activated on some configurations, resulting in
some warnings (at least with STRICT_MM_TYPECHECKS enabled) and build
errors in some circumstances. This fixes it.

This adds a vdso_base element to the mm_context_t for 32-bit compiles
(both for ARCH=powerpc and ARCH=ppc). This fixes the compile errors
that have been reported in arch/powerpc/kernel/signal_32.c.

Update comments (only) on page_table_lock and mmap_sem in arch/powerpc.
Removed the comment on page_table_lock from hash_huge_page: since it's no
longer taking page_table_lock itself, it's irrelevant whether others are; but
how it is safe (even against huge file truncation?) I can't say.

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.
