As the C6X port has been merged in this merge window, I can't easily
apply this patch to my kbuild branch and at the same time please Linus
by basing the pull request on a tagged release. So I'm going to drop the
arch/c6x part to keep the kbuild branch "pretty" and let either Mark or
Stephen send the patch to Linus directly, once he has merged the kbuild
branch. Would that work?
