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!

I applied the patch series on top of mainline and verified that the kernel
builds and boots successfully.
I also ran the following test suites on both RADIX (POWER11) and HASH
(POWER9)
MMU configurations:
- tools/testing/selftests/mm
- tools/testing/selftests/memory-hotplug
- tools/testing/selftests/powerpc/mm
- tools/testing/selftests/powerpc/cache_shape
- tools/testing/selftests/powerpc/copyloops
In addition, I executed basic sanity and stress tests, including:
stutter, eatmemory, hugepage_sanity, fork_mem, memory_api mprotect,
vatest, and several transparent-hugepage sanity checks.
All tests passed without regressions.
Regards,
Venkat
