This series is ver.3 of page table walker patchset.
In previous discussion I got an objection of moving pte handling code to
->pte_entry() callback, so in this version I've dropped all of such code.
The patchset mainly does fixing vma handling and applying page walker to
2 new users. Here is a brief overview:
patch 1: clean up
patch 2: fix bug-prone vma handling code
patch 3: add another interface of page walker
patch 4-10: clean up each of existing user
patch 11: apply page walker to new user queue_pages_range()
patch 12: allow clear_refs_pte_range() to handle thp (from Kirill)
patch 13: apply page walker to new user do_mincore()
Thanks,
Naoya Horiguchi
