Andreas Herrmann e4df1cbcc1 cpufreq / powernow-k8: Remove usage of smp_processor_id() in preemptible code 
Commit 6889125b8b
(cpufreq/powernow-k8: workqueue user shouldn't migrate the kworker to another CPU)
causes powernow-k8 to trigger a preempt warning, e.g.:

  BUG: using smp_processor_id() in preemptible [00000000] code: cpufreq/3776
  caller is powernowk8_target+0x20/0x49
  Pid: 3776, comm: cpufreq Not tainted 3.6.0 #9

Fix this by by always using work_on_cpu().
