Ok, so if there's no major objections with this set, here's my plan:

1) I'm going to queue 1-4 in a fortglx/3.12/sched-clock64 branch, I'll
send git pull requests to both Thomas and Olof, so they can both merge
the common base for the conversion code in both drivers/clocksource and
arch/arm.

2) If I can get Catalin's ack on 5/17, I'll queue it and 6/17 for
tip/timers/core.

3) I'll also queue the rest and send to Thomas or Daniel for
tip/timers/core.

That sound ok to everyone?

thanks
-john
