Subject: [PATCH v3 0/5] Cleanup and fixup for huge_memory

Hi all,
This series contains cleanups to remove dedicated macro and remove
unnecessary tlb_remove_page_size() for huge zero pmd. Also this adds
missing read-only THP checking for transparent_hugepage_enabled() and
avoids discarding hugepage if other processes are mapping it. More
details can be found in the respective changelogs. Thanks!

v2->v3:
  collect Reviewed-by and Acked-by tag
  rename transhuge_vma_enabled to transparent_hugepage_active and
add helper file_thp_enabled per David Hildenbrand

v1->v2:
  collect Reviewed-by tag
  add missing check for read-only THP per Yang Shi

Miaohe Lin (5):
  mm/huge_memory.c: remove dedicated macro HPAGE_CACHE_INDEX_MASK
  mm/huge_memory.c: use page->deferred_list
  mm/huge_memory.c: add missing read-only THP checking in
    transparent_hugepage_enabled()
  mm/huge_memory.c: remove unnecessary tlb_remove_page_size() for huge
    zero pmd
  mm/huge_memory.c: don't discard hugepage if other processes are
    mapping it
