On AMD machines, the perf stat STD output test failed like below:
$ sudo ./perf test -v 98
98: perf stat STD output linter :
--- start ---
test child forked, pid 1841901
Checking STD output: no argswrong event metric.
expected 'GHz' in 108,121 stalled-cycles-frontend # 10.88% frontend cycles idle
test child finished with -1
---- end ----
perf stat STD output linter: FAILED!
This is because there are stalled-cycles-{frontend,backend} events are
used by default. The current logic checks the event_name array to find
which event it's running. But 'cycles' event comes before those stalled
cycles event and it matches first. So it tries to find 'GHz' metric
in the output (which is for the 'cycles') and fails.
Move the stalled-cycles-{frontend,backend} events before 'cycles' so
that it can find the stalled cycles events first.
Also add a space after 'no args' test name for consistency.
