Even if we don't have any preemption, we need preempt disable/enable* to be barriers, so that we don't have things like get_user/put_user* that can cause faults and scheduling migrate into our preempt-protected* region.()

These routines enable/disable the pagefault handler. If disabled, it will* not take any locks and go straight to the fixup table.* User access methods will not sleep when called from a pagefault_disabled()* environment.
