[PATCH 0/8] BOOk3s 64 MMU code cleanup

[Aneesh Kumar K.V]

This series include changes that should help in implementing
radix MMU model. Besides that, we also try to consolidate
hash64 code into separate files wherever it simplifies
the existing code by removing #ifdef around C code. IMHO
code movement also helps in indicating supported features
on different platforms better. (Changes like moving THP to hash64
indicates that for now we only have THP implemented for hash64).

The series is on top of changes posted at

Aneesh Kumar K.V (8):
  powerp/mm: Update code comments
  powerpc/mm: add _PAGE_HASHPTE similar to 4K hash
  powerpc/mm: Use flush_tlb_page in ptep_clear_flush_young
  powerpc/mm: Move hash related mmu-*.h headers to book3s/
  powerpc/mm: Create a new headers for tlbflush for hash64
  powerpc/mm: Move hash page table related functions to pgtable-hash64.c
  powerpc/mm: THP is only available on hash64 as of now
  powerpc/mm: Use generic version of pmdp_clear_flush_young
