Nit: can we use the space a little more efficient, e.g.:

hmm_range_fault() calls find_vma() and walk_page_range() in a loop.
This is unnecessary duplication since walk_page_range() calls find_vma()
in a loop already.
Simplify hmm_range_fault() by defining a walk_test() callback function
to filter unhandled vmas.
This also fixes a bug where hmm_range_faul
