Subject: [PATCH v8 05/20] powerpc/mm: move platform specific mmu-xxx.h in
platform directories
The purpose of this patch is to move platform specific
mmu-xxx.h files in platform directories like pte-xxx.h files.
In the meantime this patch creates common nohash and
nohash/32 + nohash/64 mmu.h files for future common parts.
