From: "Kirill A. Shutemov" <kirill.shutemov@xxxxxxxxxxxxxxx>
Subject: rmap: add argument to charge compound page
We're going to allow mapping of individual 4k pages of THP compound page.
It means we cannot rely on PageTransHuge() check to decide if map/unmap
small page or THP.
The patch adds new argument to rmap functions to indicate whether we want
to operate on whole compound page or only the small page.
