[RFC PATCH 8/9] powerpc/mm/book3s-64: Move software-used bits in PTE

[Paul Mackerras]

This moves the _PAGE_BUSY, _PAGE_SPECIAL and _PAGE_SOFT_DIRTY bits
in the Linux PTE on 64-bit Book 3S systems to bit positions which
are designated for software use in the radix PTE format used by
PowerISA v3.0 CPUs in radix mode.
