But this won't work without your kernel patches right? 

If they are already in the kernel used by the person launching the selftests
then there shouldn't be any problems to report. The idea was that if the
CMT/MBM/MBA selftests fail, the message with "SNC is the problem" is only
displayed if SNC is enabled and there is no kernel support for SNC.
