[ Upstream commit f98db6013c557c216da5038d9c52045be55cd039 ]
By default, this is the same thing as switch_mm().
x86 will override it as an optimization.

mm: move use_mm/unuse_mm from aio.c to mm/2009-09-22T14:17:42ZMichael S. Tsirkin2009-09-22T00:03:51Zurn:sha1:3d2d827f5ca5e32816194119d5c980c7e04474a6
Anyone who wants to do copy to/from user from a kernel thread, needs
use_mm (like what fs/aio has). Move that into mm/, to make reusing and
exporting easier down the line, and make aio use it. Next intended user,
besides aio, will be vhost-net.
