[PATCH 0/4] Add 4 level page table for 64k book3s config

[Aneesh Kumar K.V]

This series move book3s config with 64k linux page size to a 4 level
linux page table setup. This makes it similar to PowerISA 3.0 radix
setup which inturn will enable us to support both hash and radix
MMU model using single kernel.


Aneesh Kumar K.V (3):
  powerpc/mm: Split pgtable types to separate header
  powerpc/mm: Don't have conditional defines for real_pte_t
  powerpc/mm: Switch book3s 64 with 64K page size to 4 level page table

  mm: Some arch may want to use HPAGE_PMD related values as variables
