Subject: x86: add pmd_[dirty|mkclean] for THP
MADV_FREE needs pmd_dirty and pmd_mkclean for detecting recent overwrite
of the contents since MADV_FREE syscall is called for THP page.
This patch adds pmd_dirty and pmd_mkclean for THP page MADV_FREE
support.
[akpm@xxxxxxxxxxxxxxxxxxxx: mm-fix-huge-zero-page-accounting-in-smaps-report.patch also added pmd_dirty()]
