OK, apparently we need to tell gcc explicitly to pack it on frv. I've
reproduced using the above instructions, and adding __packed solves
it. Please use the alternative patch I'll send as a follow-up in a
moment.

I have to say, this automated build testing before the patches hit
-next (indeed, almost before git send-email is finished sending out the
entire series!) is rather awesome.
