Subject: [PATCH v13 4/8] powerpc: add pmd_[dirty|mkclean] for THP
Date: Fri, 18 Jul 2014 15:53:02 +0900 [thread overview]
Message-ID: <1405666386-15095-5-git-send-email-minchan@kernel.org> (raw)
In-Reply-To: <1405666386-15095-1-git-send-email-minchan@kernel.org>
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.
