v2:
  * removed the coupled lock, replacing it with atomic counters
  * added a check for outstanding pokes before beginning the
    final transition to avoid extra wakeups
  * made the cpuidle_coupled struct completely private
  * fixed kerneldoc comment formatting
  * added a patch with a helper function for resynchronizing
    cpus after aborting idle
  * added a patch (not for merging) to add trace events for
    verification and performance testing

I forgot to mention, this patch series is on v3.3-rc7, and will
conflict with the cpuidle timekeeping patches.  If those go in first
(which is likely), I will rework this series on top of it.  I left it
on v3.3-rc7 now to make testing easier.

I have re-based your series against Len Browns
next branch [1] which has time keeping and other cpuidle patches.
Have also folded the CPU hotplug fix which I posted in the
original coupled idle patch.

If you want, the updated branch can be pulled from:

git://gitorious.org/omap-sw-develoment/linux-omap-dev.git
for_3.5/coupled_cpuidle-rebase
