-From: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com>
-Subject: cpufreq, ondemand: Use a parameter for down differential
-
-Use a parameter for down differential, instead of hardcoded 10%. Follow-on
-patch changes the down-differential dynamically, based on whether
-we are using idle micro-accounting or not.
