A quick survey of the wreckage:

- Dmitry's input git tree breaks a bit

- five of Greg's USB patches need fixing

- a few random -mm patches need touchups

- The hrtimer+dynticks i386 patch takes rather a hit and will need redoing.

So, not too bad at all. It's a bit rough on the poor old arch maintainers,
but it's pretty simple stuff.

I'd say let's do it...
