Subject[PATCH v2 0/6] Fix some bugs related to ramp and dax
Date
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().

Changes in 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: page_vma_mapped: support checking if a pfn is mapped into a vma
mm: rmap: introduce pfn_mkclean_range() to cleans PTEs
dax: fix missing writeprotect the pte entry
