[GIT PULL] First set of timekeeping changes for 3.13

[GIT PULL] First set of timekeeping changes for 3.13

[John Stultz]

Hey Thomas, Ingo,
    So these were items I had hoped to get merged in 3.12, but I'm
guessing got buried in Thomas inbox while he was traveling/busy (and its
my fault for not cc'ing Ingo). So now 3.12-rc1 is out, I wanted to send
this in for tip/timers/core right away so these don't get missed in this
next cycle.

Please let me know if there are any objections or issues with these changes.

thanks
-john
