 *
 * IMPORTANT: we should normally not directly call this function, instead
 * this is only a common interface to implement arch-specific
 * walker. Please use hugetlb_walk() instead, because that will attempt to
 * verify the locking for you.
 *
 * Since this function will walk all the pgtable pages (including not only
 * high-level pgtable page, but also PUD entry that can be unshared
 * concurrently for VM_SHARED), the caller of this function should be
 * responsible of its thread safety.  One can follow this rule:
 *
 *  (1) For private mappings: pmd unsharing is not possible, so holding the
 *      mmap_lock for either read or write is sufficient. Most callers
 *      already hold the mmap_lock, so normally, no special action is
 *      required.
 *
 *  (2) For shared mappings: pmd unsharing is possible (so the PUD-ranged
 *      pgtable page can go away from under us!  It can be done by a pmd
 *      unshare with a follow up munmap() on the other process), then we
 *      need either:
 *
 *     (2.1) hugetlb vma lock read or write held, to make sure pmd unshare
 *           won't happen upon the range (it also makes sure the pte_t we
 *           read is the right and stable one), or,
 *
 *     (2.2) hugetlb mapping i_mmap_rwsem lock held read or write, to make
 *           sure even if unshare happened the racy unmap() will wait until
 *           i_mmap_rwsem is released.
 *
 * Option (2.1) is the safest, which guarantees pte stability from pmd
 * sharing pov, until the vma lock released.  Option (2.2) doesn't protect
 * a concurrent pmd unshare, but it makes sure the pgtable page is safe to
 * access.
