[PATCH v8 0/2] hugetlb MADV_DONTNEED fix and zap_page_range cleanup

[Mike Kravetz]

Sending v8 as a two patch series.
Patch 1 addressed the huegtlb MADV_DONTNEED bug and should eventually go
to stable releases.
Patch 2 is cleanup which removes zap_page_range and changes as all callers
to use the new zap_vma_range routine as they only pass ranges within a
single vma.

These changes inspired by discussions with Nadav and Peter.

Andrew, I would suggest not replacing the patch currently in
mm-hotfixes-unstable branch until there is some feedback here.

Mike Kravetz (2):
  hugetlb: don't delete vma_lock in hugetlb MADV_DONTNEED processing
  mm: remove zap_page_range and change callers to use zap_vma_range
