Perf test case 83: perf stat CSV output linter might fail on s390. The reason for this is the output of the command
./perf stat -x, -A -a --no-merge true
which depends on a .config file setting. When CONFIG_SCHED_TOPOLOGY is set, the output of above perf command is
CPU0,1.50,msec,cpu-clock,1502781,100.00,1.052,CPUs utilized
When CONFIG_SCHED_TOPOLOGY is *NOT* set the output of above perf command is
0.95,msec,cpu-clock,949800,100.00,1.060,CPUs utilized
Fix the test case to accept both output formats.
Output before: # perf test 83 83: perf stat CSV output linter : FAILED! #
Output after: # ./perf test 83 83: perf stat CSV output linter : Ok #
Fixes: ec906102e5b7 ("perf test: Fix "perf stat CSV output linter" test on s390")
