[PATCH 0/5] Some cleanups for hugetlb

[Miaohe Lin <linmiaohe@huawei.com>]

Hi all,
This series contains cleanups to remove unnecessary VM_BUG_ON_PAGE, use
helper function and so on. I also collect some previous patches into this
series in case they are forgotten.
More details can be found in the respective changelogs. Thanks!

  mm/hugetlb: use some helper functions to cleanup code
