Subject: perf list: Place the header text in its right position
X-Git-Tag: omap-for-v4.2/o2_dc~146^2~66^2~4
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=619a303c1b8bd22abc549477d038ef9b5c1fe1bd;p=pandora-kernel.git

perf list: Place the header text in its right position

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]
   instructions                                       [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-load-misses                              [Hardware cache event]
   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]
   L1-dcache-stores                                   [Hardware cache event]

After this patch:

 $ perf list hw L1-dcache*

 List of pre-defined events (to be used in -e):              <-- correct position

   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]
   instructions                                       [Hardware event]
   stalled-cycles-backend OR idle-cycles-backend      [Hardware event]
   stalled-cycles-frontend OR idle-cycles-frontend    [Hardware event]

   L1-dcache-load-misses                              [Hardware cache event]
   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]
   L1-dcache-stores                                   [Hardware cache event]
