Hi Peter,

Subject: [PATCH] selftests/resctrl: Use correct exit code when tests fail

Use ksft_finished() after running tests so that resctrl_tests doesn't return exit code 0 when tests fail.

Consequently, report the MBA and MBM tests as skipped when running on non-Intel hardware, otherwise resctrl_tests will exit with a failure code.
