   8           CPU idle is a generic framework for supporting software-controlled
   9           idle processor power management.  It includes modular cross-platform
  10           governors that can be swapped during runtime.

  12           If you're using an ACPI-enabled platform, you should say Y here.

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