[Test Case]
Testing fastsleep
-----------------
With these patches cpuidle framework picks up fastsleep as one of the idle states. You can observe the cpus entering fastsleep by checking
/sys/devices/system/cpu/cpuXX/cpuidle/state2/name. This should show FastSleep.
Then while system is idle check /sys/devices/system/cpu/cpuXX/cpuidle/state2/time increment over time
This shows the amount of time a particular cpu was in fastsleep.
Testing Winkle
--------------
With these patches, offline cpus enter winkle. So test this by offlining and onlining cpus.
ppc64_cpu --cores-on=1
ppc64_cpu --cores-on=X where X is the total number of cores available in the machine.

This is a feature request to enable power management features
fastsleep and winkle cpuidle states in ubuntu -14.04.02 kernel. The
cpuidle state management patches have been posted to Linux Kernel
Community.
