Peter Xu 59caf93f36 BACKPORT: FROMGIT: hugetlb: pass vma into huge_pte_alloc() and huge_pmd_share() 
Patch series "hugetlb: Disable huge pmd unshare for uffd-wp", v4.

This series tries to disable huge pmd unshare of hugetlbfs backed memory
for uffd-wp.  Although uffd-wp of hugetlbfs is still during rfc stage, the
idea of this series may be needed for multiple tasks (Axel's uffd minor
fault series, and Mike's soft dirty series), so I picked it out from the
larger series.

This patch (of 4):

It is a preparation work to be able to behave differently in the per
architecture huge_pte_alloc() according to different VMA attributes.

Pass it deeper into huge_pmd_share() so that we can avoid the find_vma() call.
