    perf list: Place the header text in its right position · 619a303c
    Yunlong Song authored
    The hearer text 'List of pre-defined events (to be used in -e):' is
    placed in an improper function, which causes an abnormal output, e.g.
    'perf list hw' shows no guiding text at all, and 'perf list hw
    L1-dcache*' shows the guiding text incorrectly in the middle of the
    output.
    
    Example
    Before this patch:
    
     $ perf list hw L1-dcache*
    
       branch-instructions OR branches                    [Hardware event]
       branch-misses                                      [Hardware event]
       bus-cycles                                         [Hardware event]
       cache-misses                                       [Hardware event]
       cache-references                                   [Hardware event]
       cpu-cycles OR cycles                               [Hardware event]

       stalled-cycles-backend OR idle-cycles-backend      [Hardware event]
       stalled-cycles-frontend OR idle-cycles-frontend    [Hardware event]
    
     List of pre-defined events (to be used in -e):              <-- incorrect position

       L1-dcache-loads                                    [Hardware cache event]
       L1-dcache-prefetch-misses                          [Hardware cache event]
       L1-dcache-prefetches                               [Hardware cache event]
       L1-dcache-store-misses                             [Hardware cache event]
