Subject: [PATCH 3.16 067/131] blackfin: drop pte_file()

3.16.59-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: "Kirill A. Shutemov" <kirill.shutemov@...ux.intel.com>

commit 2bc6ff14d46745a7728ed4ed90c5e0edca91f52e upstream.

We've replaced remap_file_pages(2) implementation with emulation.  Nobody
creates non-linear mapping anymore.
