Changes from V1:
* Update "powerpc/mm: Convert early cpu/mmu feature check to use the new helpers"
  based on resend code changes in this area.

We now do feature fixup early and hence we can reduce the usage of
 __cpu/__mmu_has_feature.

Aneesh Kumar K.V (5):
  powerpc/mm: Add __cpu/__mmu_has_feature
  powerpc/mm: Convert early cpu/mmu feature check to use the new helpers
  powerpc/mm/radix: Add radix_set_pte to use in early init
  powerpc: Call jump_label_init early
  powerpc/mm: Catch the usage of cpu/mmu_has_feature before jump label
    init

Kevin Hao (5):
  jump_label: make it possible for the archs to invoke jump_label_init()
    much earlier
  powerpc: kill mfvtb()
  powerpc: move the cpu_has_feature to a separate file
  powerpc: use the jump label for cpu_has_feature
  powerpc: use jump label for mmu_has_feature
