This seems to work at least for my userfaultfd test on shmem, however I don't
fully understand the commit message [1] on: How do we guarantee we're not
moving a thp pte?

move_page_tables() checks for pmd_trans_huge() and ends up calling
move_huge_pmd if it is a THP entry.

Sorry to be unclear: what if a huge pud thp?
