[PATCH v4 00/13] pagewalk: improve vma handling, apply to new users

This series is ver.4 of page table walker patchset.
I reflected comments in the previous version (thanks Kirill, Jerome).
And rebased onto v3.16-rc3. Recently code around queue_pages_range()
is changed by commit d05f0cdcbe63 "mm: fix crashes from mbind() merging
vma", which affects this series a little.

Thanks,
Naoya Horiguchi
