Sorry for the noise.

Ian has addressed my concerns. The patch looks good to me now.
It also fixes a "Failed" on my Cascade Lake machine.

Tested-by: Kan Liang <kan.liang@...ux.intel.com>

But for long term, we probably need a better solution to avoid keeping
adding such non-architectural events in the test case.

Thanks,
Kan
