The quilt patch titled
Subject: mm/mmap: change do_vmi_align_munmap() for maple tree iterator changes
has been removed from the -mm tree. Its filename was
mm-mmap-change-do_vmi_align_munmap-for-maple-tree-iterator-changes.patch
This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm/mmap: change do_vmi_align_munmap() for maple tree iterator changes
Date: Thu, 18 May 2023 10:55:31 -0400
The maple tree iterator clean up is incompatible with the way
do_vmi_align_munmap() expects it to behave. Update the expected behaviour
to map now since the change will work currently.
