[GIT PULL] Timekeeping changes for 3.4

[GIT PULL] Timekeeping changes for 3.4

[john stultz]

Hey Thomas,
	Here's the first chunk of my big timekeeping change queue, for 3.4.
Most of it should be fairly straight forward cleanups, moving values
into the timekeeper structure and changing the locking away from
xtime_lock.

Again, since tip/timers/core hasn't been updated since 3.3 was out,
these are against Linus' head (actually, from a week or so ago). Let me
know if you'd like me to base them off of something else.

Also, the more aggressive changes that will allow for reduced lock hold
times, which I'm holding off for 3.5 or later, can be found here if you
want to take a look at them, or possibly merge them earlier into a
3.4-rt tree for extra testing:

thanks
