Subject: [PATCH 00/10] mm/hugetlb: code refine and simplification

Following are some cleanup for hugetlb.

Simple test with tools/testing/selftests/vm/map_hugetlb pass.

Wei Yang (10):
  mm/hugetlb: not necessary to coalesce regions recursively
  mm/hugetlb: make sure to get NULL when list is empty
  mm/hugetlb: use list_splice to merge two list at once
  mm/hugetlb: count file_region to be added when regions_needed != NULL
  mm/hugetlb: remove the redundant check on non_swap_entry()
  mm/hugetlb: remove redundant huge_pte_alloc() in hugetlb_fault()
  mm/hugetlb: a page from buddy is not on any list
  mm/hugetlb: return non-isolated page in the loop instead of break and
    check
  mm/hugetlb: narrow the hugetlb_lock protection area during preparing
    huge page
  mm/hugetlb: not necessary to abuse temporary page to workaround the
    nasty free_huge_page
