This series converts powerpc to default topdown mmap layout.

powerpc provides its own arch_get_unmapped_area() only when
slices are needed, which is only for book3s/64. First part of
the series moves slices into book3s/64 specific directories
and cleans up other subarchitectures.

Then a small modification is done to core mm to allow
powerpc to still provide its own arch_randomize_brk()

Last part converts to default topdown mmap layout.

A nice series but will clash badly with the CONFIG_HASH_MMU
series of course. One will have to be rebased if they are
both to be merged.

No worry, it should be an issue.

If you already forsee that series being merged soon, I can rebase my 
series on top of it just now.
