3.11.10.3 -stable review patch.  If anyone has any objections, please let me 
know.

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

From: Catalin Marinas <[email protected]>

commit 4f00130b70e5eee813cc7bc298e0f3fdf79673cc upstream.

This provides better performance compared to Device GRE and also allows
unaligned accesses. Such memory is intended to be used with standard RAM
(e.g. framebuffers) and not I/O.
