Subject: [PATCH 0/6] A few cleanup patches for memory-failure

Hi everyone,
This series contains a few cleanup patches to use __PageMovable() to
detect non-lru movable pages, use num_poisoned_pages_sub() to reduce
multiple atomic ops overheads and so on. More details can be found in
the respective changelogs.
Thanks!

Miaohe Lin (6):
  mm, hwpoison: use ClearPageHWPoison() in memory_failure()
  mm, hwpoison: use __PageMovable() to detect non-lru movable pages
  mm, hwpoison: use num_poisoned_pages_sub() to decrease
    num_poisoned_pages
  mm, hwpoison: avoid unneeded page_mapped_in_vma() overhead in
    collect_procs_anon()
  mm, hwpoison: check PageTable() explicitly in hwpoison_user_mappings()
  mm, hwpoison: cleanup some obsolete comments
