[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.
