To quote admin/notes/git-workflow:

Backporting to release branch
=============================

If you have applied a fix to the master, but then decide that it should
be applied to the release branch, too, then

cd ~/emacs/master
git log

and find the commit you're looking for.  Then find the commit ID,
which will look like

commit 958b768a6534ae6e77a8547a56fc31b46b63710b

cd ~/emacs/emacs-28
git cherry-pick -xe 958b768a6534ae6e77a8547a56fc31b46b63710b

and add "Backport:" to the commit string.  Then

git push
