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.
