oh gee, you don't want to look.  It should all be in
http://userweb.kernel.org/~akpm/stuff/patch-scripts.tar.gz

But really it's just the one script, pull-git-patches, below.  That
thing's been hacked around so much that I daren't breathe on it.

Fortunately as long as Stephen Rothwell is producing linux-next I don't
have much need for it any more.
