Look at patches http://patchwork.ozlabs.org/patch/248920/ and followup,
he basically walks the page tables here in a slightly different way than
Paul does in H_ENTER. It's more like gup_fast. It will need to handle
concurrent split/collapse etc... as well which it doesn't right now.
I'm considering merging Alexei stuff first (provided I don't find major

Ok, for now ignore Alexey stuff, there's enough issues in it that I can't
quite merge it yet. Just handle my other comments.
Cheers,
