There are two types of iterators mas and vmi in the current code. If the

using mas directly as possible.
Keep using mas for the mt_detach tree, since it doesn't come from the mm
structure.
Remove as many uses of mas as possible, but we will still have a few that
must be passed through in unmap_vmas() and free_pgtables().
Also introduce vma_iter_reset, vma_iter_{prev, next}_range_limit and
vma_iter_area_{lowest, highest} helper functions for using the vma
interator.
I assume Liam's earlier request still applies?
