[PATCH v2 00/10] Misc powerpc selftests kernel fixes and cleanups

["Ritesh Harjani (IBM)" <ritesh.list@gmail.com>]

v1->v2:

- dropped debug_vm_pgtable patch which adds a testcase to simulate the
  failure scenario. Since it belongs to linux-mm, I will send that out
  separately.
- Modified Patch-2 in this series to also cover PMD device migration
  entry (in addition to PMD THP migration entry). Hence dropped the
  previous RB tag.
- Added a new Patch-3 to fix another selftests WARNING.
- Fixed commit subject of Patch-10.
- Changed subject pre-fix of few patches to be consistent with others
  (powerpc/64s) 
- Added RB tags

This patch series addresses selftests issues w.r.t warnings or
VM_BUG_ONs seen mainly on book3s64 powerpc kernel. This also carries
cleanups and refactoring changes which I identified while reviewing
other's patches and/or during code walkthrough.

Suggestions and feedback are welcome!
