Meta-comment, now that UFO is gone from mainline, I'm wondering if I
should just delete it from 4.4 and 4.9 as well.  Any objections for
that?  I'd like to make it easy to maintain these kernels for a while,
and having them diverge like this, with all of the issues around UFO,
seems like it will just make life harder for myself if I leave it in.

Any opinions?

thanks,
