[PATCH v13 4/8] powerpc: add pmd_[dirty|mkclean] for THP

2014-07-17 Thread Minchan Kim

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. Cc: Benjamin Herrenschmidt Cc: Paul Mackerras Cc: "Aneesh Kumar K.V" Cc: linuxppc-d
