Kirill A. Shutemov c389a250ab mm, thp: do not access mm->pmd_huge_pte directly 
Currently mm->pmd_huge_pte protected by page table lock.  It will not
work with split lock.  We have to have per-pmd pmd_huge_pte for proper
access serialization.

For now, let's just introduce wrapper to access mm->pmd_huge_pte.
