Message

The first patch uses correct flush tlb functions when move page tables,
and second patch is a small tlb flush optimization for hugepage on arm64.

v2:
- drop uncorrected move_normal_pmd/pud() changes
- add flush_hugetlb_tlb_range() on arm64 instead of changing generic
  flush_tlb_range()
- collect RB/ACK

Kefeng Wang (2):
  mm: hugetlb: use flush_hugetlb_tlb_range() in
    move_hugetlb_page_tables()
  arm64: hugetlb: enable __HAVE_ARCH_FLUSH_HUGETLB_TLB_RANGE
