I usually just do:

git push acme.korg perf/urgent

or

git push acme.korg perf/urgent

[acme@...et linux]$ git remote -v | grep korg
acme.korg	gitolite@...olite.kernel.org:/pub/scm/linux/kernel/git/acme/linux.git (fetch)
acme.korg	gitolite@...olite.kernel.org:/pub/scm/linux/kernel/git/acme/linux.git (push)
[acme@...et linux]$ 

Or some other branch, acme/master isn't updated. I guess I should do
like tip/master, and always have acme/master with acme/perf/core merged
with acme/perf/urgent, but for now, just consider acme/perf/urgent and
acme/perf/core.
