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

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

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