 + Added FIOPS IO scheduler.
 + Added GPU Overclock from 450 to 500 MHz.
 + Added autoSMP hotplug.
-+ Added CPU voltage control.
++ Added CPU voltage control for big cores.
 + Added Sweep2Wake and DoubleTap2Wake - May not be fully functional, my prox sensor is smashed.
++ Added Little CPU core voltage control.
