[Andrew Morton]

The quilt patch titled
     Subject: mm/mmap: change do_brk_munmap() to use do_mas_align_munmap()
has been removed from the -mm tree.  Its filename was
     mm-mmap-change-do_brk_munmap-to-use-do_mas_align_munmap.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_brk_munmap() to use do_mas_align_munmap()
Date: Tue, 6 Sep 2022 19:48:52 +0000

do_brk_munmap() has already aligned the address and has a maple tree state
to be used.  Use the new do_mas_align_munmap() to avoid unnecessary
alignment and error checks.
