Subject: [PATCH v2 00/15] Refactor pgalloc stuff

This series converts book3e64 to pte_fragment and refactor
things that are common among subarches.

Changes in v2:
- Rebased on latest merge branch (b251649c77625b7ad4430e518dc0f1608be9edf4)
- Resolved conflicts, especially due to the addition of MAX_PHYSMEM_BITS in
asm/nohash/64/mmu.h ==> moved it to asm/nohash/mmu-book3e.h
- compilation test at http://kisskb.ellerman.id.au/kisskb/head/cf0b6c1ff5ca934bbe02f88b1b1ba533b386225e/
