Also, for the small requests: since you are at it, can you add the code
in a new file under virt/kvm/?

Hm... only if I can make hva_to_pfn() and probably a handful of other
things non-static?

Yes, I think sooner or later we also want all pfn stuff in one file 
(together with MMU notifiers) and all hva stuff in another; so for now 
you can create virt/kvm/hva_to_pfn.h, or virt/kvm/mm.h, or whatever 
color of the bikeshed you prefer.

OK... let's start with this.
