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
