The patch titled
Subject: mm/debug_vm_pgtable: use struct pgtable_debug_args in PTE modifying tests
has been removed from the -mm tree. Its filename was

From: Gavin Shan <gshan@redhat.com>
Subject: mm/debug_vm_pgtable: use struct pgtable_debug_args in PTE modifying tests
This uses struct pgtable_debug_args in PTE modifying tests. The allocated
page is used as set_pte_at() is used there. The tests are skipped if the
allocated page doesn't exist. Besides, the unused variable @ptep and
@pte_aligned in debug_vm_pgtable() are dropped.
