Allow preemption while doing a lazy mmu update.

That's probably OK, just a bit late. If Thomas signs off on them then i guess it might be OK later in the window - he's the one who was struggling with paravirt lazy mmu fallout in the past. Thomas?

Those patches were actually in response to PeterZ's (and NickP+AKPM) concerns about adding preempt-disabled section to apply_to_page_range(). He's acked them now.
