David Hildenbrand 2cb7c9cb42 sched/preempt, mm/kmap: Explicitly disable/enable preemption in kmap_atomic_* 
The existing code relies on pagefault_disable() implicitly disabling
preemption, so that no schedule will happen between kmap_atomic() and
kunmap_atomic().

Let's make this explicit, to prepare for pagefault_disable() not
touching preemption anymore.
