The access problem could be solved by none of us having access to the
repo, if the git.kernel.org admins are willing to set up a mirror of
the github repo, a cronjob running git-fetch with the appropriate
parameters to just fetch the master (or everything, but only master is
needed). Updating such a mirror with a daily cronjob would be more
than enough.

Less seriously but worth pointing out: It could also be solved by just
setting the user:password to foo:bar and publishing that in the
description & setting the repo to non-fast-forward only. This will
only be used by the git.git repo, which'll point at a specific sha1 in
its history, wouldn't that be a nice demo of the whole "give the repo
to your worst enemy but as long as you have the sha ... " parable
