CPU STATS

    First field is a sched_yield() statistic:
         1) # of times sched_yield() was called

    Next three are schedule() statistics:
         2) This field is a legacy array expiration count field used in the O(1)
      scheduler. We kept it for ABI compatibility, but it is always set to zero.
         3) # of times schedule() was called
         4) # of times schedule() left the processor idle

    Next two are try_to_wake_up() statistics:
         5) # of times try_to_wake_up() was called
         6) # of times try_to_wake_up() was called to wake up the local cpu

  | Next three are statistics describing scheduling latency:                       |
  |      7) sum of all time spent running by tasks on this processor (in jiffies)  |
  |      8) sum of all time spent waiting to run by tasks on this processor (in    |
