I've applied these to a testing branch in my usb tree, and if they
survive the 0-day bot, I'll move them to a branch that you can pull from
that will not change.

Oh, I had to add a follow-on patch to fix up a gcc warning that really
wasn't a warning, but it saves us problems of people complaining about
it.
