  	  CPU idle is a generic framework for supporting software-controlled
  	  idle processor power management.  It includes modular cross-platform
  	  governors that can be swapped during runtime.
  
  	  If you're using an ACPI-enabled platform, you should say Y here.

           Allows the cpuidle framework to use different drivers for each CPU.
           This is useful if you have a system with different CPU latencies and
           states. If unsure say N.
