  cpupower : Fix cpupower working when cpu0 is offline
  
  cpuidle_monitor used to assume that cpu0 is always online which is not
  a valid assumption on POWER machines. This patch fixes this by getting
  the cpu on which the current thread is running, instead of always using
  cpu0 for monitoring which may not be online.

  cpupower : Fix cpupower working when cpu0 is offline
  
  cpuidle_monitor used to assume that cpu0 is always online which is not
  a valid assumption on POWER machines. This patch fixes this by getting
  the cpu on which the current thread is running, instead of always using
  cpu0 for monitoring which may not be online.
