Since last time:
- Rebased on top of Aneesh's series "[PATCH V2 1/4] powerpc/mm/hugetlb:
  Update huge_ptep_set_access_flags to call __ptep_set_access_flags"

Thanks,
Nick

    full case
  powerpc/64s/radix: prefetch user address in update_mmu_cache
  powerpc/64s/radix: avoid ptesync after set_pte and
    ptep_set_access_flags
