[GIT PULL] rtc/time work possibly for 3.3

[GIT PULL] rtc/time work possibly for 3.3

[john stultz]

Hey Thomas,
	This is a little late in the merge window, so let me know and I'll
rework this queue for 3.4.

I've got two main items here:
1) Improved version of Neil's fix for the RTC queue getting jammed up if
RTC time was set forward. This resolves the issues that required it be
reverted right before 3.2

2) Timekeeping core cleanup. These are fairly straight forward reworking
of the timekeeping code, moving all the inter-connected variables into
the timekeeper structure, and splitting up the xtime_lock usage into a
separate timekeeper lock and ntp lock. This is in preparation for the
timekeeping lock hold time reduction changes I want to push out to 3.4.

These are against linus's HEAD right now, as tip/timers/core has all
been merged and is a bit behind. Let me know if you'd rather I rebase
these ontop of something else.

Anyway, they are available in the git repository at:
  git://git.linaro.org/people/jstultz/linux.git fortglx/3.3/tip/timers/core

Shortlog is here:
