This series is based on next-20220225.

Patch 1-2 fix a cache flush bug, because subsequent patches depend on
those on those changes, there are placed in this series.  Patch 3-4
are preparation for fixing a dax bug in patch 5.  Patch 6 is code cleanup
since the previous patch remove the usage of follow_invalidate_pte().

v3:
- Based on next-20220225.

v2:
- Avoid the overly long line in lots of places suggested by Christoph.
- Fix a compiler warning reported by kernel test robot since pmd_pfn()
  is not defined when !CONFIG_TRANSPARENT_HUGEPAGE on powerpc architecture.
- Split a new patch 4 for preparation of fixing the dax bug.

Muchun Song (6):
  mm: rmap: fix cache flush on THP pages
  dax: fix cache flush on PMD-mapped pages
  mm: rmap: introduce pfn_mkclean_range() to cleans PTEs
  mm: pvmw: add support for walking devmap pages
  dax: fix missing writeprotect the pte entry
