This patch removes the 'cpu_id' parameter of the clock_*
trace point, based on the ideas below:

- the cpu_id which is passed to trace point is always the current
  cpu
- the current cpu info has been included into the trace result already
- smp_processor_id() can't be used safely in preemptible context.

Do you know if these changes wont break powertop?
