Grudging okay - so irritating to have to do this!
We have different ideas of what's a good cleanup
(pte -> old/new), but if you wish.
I'd much rather you'd got rid of move_pte's prot argument,
that can be taken from the old_vma you're now having to pass
(because of your debug additions to page_remove_rmap).
Grudging okay: thanks for fixing it.
