Hi Linus !
This is the branch I mentioned in my other pull request which contains
our improved cpuidle support for the "powernv" platform
(non-virtualized). It adds support for the "fast sleep" feature of the
processor which provides higher power savings than our usual "nap" mode
but at the cost of losing the timers while asleep, and thus exploits the
new timer broadcast framework to work around that limitation.
It's based on a tip timer tree that you seem to have already merged
Cheers,
Ben.
