  powerpc/mm: drop __bad_pte()
  powerpc/mm: define __pud_free_tlb() at all time on nohash/64
  powerpc/mm: convert Book3E 64 to pte_fragment
  powerpc/mm: move pgtable_t in asm/mmu.h
  powerpc/mm: get rid of nohash/32/mmu.h and nohash/64/mmu.h
  powerpc/Kconfig: select PPC_MM_SLICES from subarch type
  powerpc/book3e: move early_alloc_pgtable() to init section
  powerpc/mm: don't use pte_alloc_kernel() until slab is available on
    PPC32
  powerpc/mm: inline pte_alloc_one_kernel() and pte_alloc_one() on PPC32
  powerpc/mm: refactor pte_alloc_one() and pte_free() families
    definition.
  powerpc/mm: refactor definition of pgtable_cache[]
  powerpc/mm: Only keep one version of pmd_populate() functions on
