3.16.59-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: "Kirill A. Shutemov" <kirill.shute...@linux.intel.com>
commit 22f9bf3950f20d24198791685f2dccac2c4ef38a upstream.
We've replaced remap_file_pages(2) implementation with emulation. Nobody
creates non-linear mapping anymore.
