Subject: [PATCH] [PATCH] Use activate_mm() in fs/aio.c:use_mm()

activate_mm() is not the right thing to be using in use_mm().  It should be
switch_mm().

On normal x86, they're synonymous, but for the Xen patches I'm adding a
hook which assumes that activate_mm is only used the first time a new mm
is used after creation (I have another hook for dealing with dup_mm).  I
think this use of activate_mm() is the only place where it could be used
a second time on an mm.

>From a quick look at the other architectures I think this is OK (most
simply implement one in terms of the other), but some are doing some
subtly different stuff between the two.
