so this changed current 'not supported' output:

   <not supported>      stalled-cycles-frontend  
   <not supported>      stalled-cycles-backend   


into

                 0      stalled-cycles-frontend                                     
                 0      stalled-cycles-backend    #   0.00% backend cycles idle

haven't tried with cgroup, but I think that removing
above hunk will not do any good to it..
