Changes in v2 from the cover letter
- 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!
