Changes in v3:
- Patch 1: recheck the PMD with pmd_none(), as only a zap can change
it and a zap leaves it none (Lance Yang).
- Link to v2:

Changes in v2:
- Add patch 2, the page table deposit for ppc64 hash, reported by
Sashiko.
- Patch 1: name panthor instead of drm_gem_shmem as the driver whose
stale child mapping reaches freed pages: drm_gem_shmem keeps the
pages of a purged object until the last mapping goes away.

Please stop sending new versions of a patchset repeatedly.
Wait at least a day for others to catch up.

Please slow down a bit. You don't need to respin every few
hours. That just makes everyone start over ...
Post a version, wait for feedback, then revise. Twice a week
is plenty, honestly :)
Cheers, Lance
Thanks.
