Hi Linus,

OK, I think we've identified the ordering issues and I have a patch out
pending testing from Dominik (hopefully tonight). I'd like to hold off
one more day on reverting if you're OK with that.

At RC5, we're certainly further into the RC cycle than I want to see
these changes. So if you just want to call it now, I understand and I'll
send you the revert pull request. If you can give me another day, I
think we may finally have found the end of this loose string.

Thanks,
