Yes, for the stable branches, we don't care about master. I use
$UPSTREAM as a variable for the git --log, upstream is passed as an
argument for genspec and defined in Makefile.common, though that should
be broken out into an included file just for variables likely to change
by branch.
I might argue that most people don't care about upstream/master because
if you are working off of this tree directly, or if you cloned it
through gitlab to your own account, origin/master would be preferred.
upstream/master was a relic from when we asked people to actually add a
separate remote, which hasn't really been the case in a year.
