Subject: [PATCH, REBASED 0/8] Transparent huge page cache: phase 0, prep work

From: "Kirill A. Shutemov" <kirill.shutemov@...ux.intel.com>

[ no changes since last post, only rebased to v3.11-rc1 ]

My patchset which introduces transparent huge page cache is pretty big and
hardly reviewable. Dave Hansen suggested to split it in few parts.

This is the first part: preparation work. I think it's useful without rest
patches.

There's one fix for bug in lru_add_page_tail(). I doubt it's possible to
trigger it on current code, but nice to have it upstream anyway.
Rest is cleanups.

Patch 8 depends on patch 7. Other patches are independent and can be
applied separately.

Please, consider applying.

Kirill A. Shutemov (8):
  mm: drop actor argument of do_generic_file_read()
  thp, mm: avoid PageUnevictable on active/inactive lru lists
  thp: account anon transparent huge pages into NR_ANON_PAGES
  mm: cleanup add_to_page_cache_locked()
  thp, mm: locking tail page is a bug
  thp: move maybe_pmd_mkwrite() out of mk_huge_pmd()
  thp: do_huge_pmd_anonymous_page() cleanup
  thp: consolidate code between handle_mm_fault() and
    do_huge_pmd_anonymous_page()
