The quilt patch titled
Subject: mm: add DEVICE_ZONE to FOR_ALL_ZONES
has been removed from the -mm tree. Its filename was
mm-add-device_zone-to-for_all_zones.patch
This patch was dropped because it was merged into the mm-hotfixes-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm: add DEVICE_ZONE to FOR_ALL_ZONES
Date: Sun, 7 Aug 2022 15:44:42 +0000
FOR_ALL_ZONES should be consistent with enum zone_type. Otherwise,
__count_zid_vm_events have the potential to add count to wrong item when
zid is ZONE_DEVICE.
