getting little tired of this:
  http://marc.info/?l=linux-kernel&m=145076648115589&w=2


first patch in your perf/stat-metrics-12:

[jolsa@...va perf]$ ./perf stat -e instructions,cycles  kill
kill: not enough arguments

 Performance counter stats for 'kill':

           772,743      instructions              #    0.82  insn per cycle         
                                                                                    
           947,484      cycles
