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] Signed-off-by: Yunlong Song <yunlong.song@huawei.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/r/1423833115-11199-8-git-send-email-yunlong.song@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
