perf test: Make the rdpmc test honour 'verbose' mode
It was unconditionally printing debug stuff when in non -v mode we should just print the name and result of the test. Now: [root@sandy ~]# perf test rdpmc 6: x86 rdpmc test: Ok [root@sandy ~]# perf test -v rdpmc 6: x86 rdpmc test: --- start --- 0: 6030 1: 60030 2: 600050 3: 6000056 4: 60000070 5: 600000266 ---- end ---- x86 rdpmc test: Ok [root@sandy ~]# Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-0tjedaozsy9oarq30nvzg74b@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
