Can you add some context that these patches do not need additional
approval for people who are already listed in the MAINTAINERS file.
That is, if Joe Contributor sends us a patch by e-mail, we aren't
automatically going to apply it.

Other than that, this is nice, it makes me want to go multi-arch
something.  :)
