Paul Mackerras c915df162d powerpc/mm/book3s-64: Shuffle read, write, execute and user bits in PTE ... This moves the _PAGE_EXEC, _PAGE_RW and _PAGE_USER bits around in the Linux PTE on 64-bit Book 3S systems to correspond with the bit positions used in radix mode by PowerISA v3.0 CPUs. This also adds a _PAGE_READ bit corresponding to the read permission bit in the radix PTE. _PAGE_READ is currently unused but could possibly be used in future to improve pte_protnone().
