Re: [PATCH v4 0/7] Event parsing fixes

There is one small difference where it now shows "stalled-cycles-..."
as <not supported> events, when before it just didn't show them at all when
they weren't supported:

  $ perf stat -- true

  Performance counter stats for 'true':

              0.66 msec task-clock                       #    0.384 CPUs utilized

           978,399      cpu_core/instructions/           #    1.02  insn per cycle            
     <not counted>      cpu_atom/cycles/                                                        (0.00%)
           959,722      cpu_core/cycles/                 #    1.458 GHz                       
   <not supported>      cpu_atom/stalled-cycles-frontend/                                      
   <not supported>      cpu_core/stalled-cycles-frontend/                                      

I don't think that's a big deal though and could probably be fixed up
later if we really want to.

I would prefer if that was fixed up. That's quite ugly for the default
view on x86/Intel.
