yes, and we may have to backtrack and find some other way to implement
this if he is opposed, as he in the past didn't like
perf_event_attr.type namespace being used by userspace only records such
as PERF_RECORD_FINISHED_ROUND, PERF_RECORD_COMPRESSED, etc.
In this case its different, I think its ok as we already have
PERF_MEM_SNOOPX_FWD and PERF_MEM_SNOOPX_PEER probably will be emitted by
the some of the architectures, from the kernel, right?

Thanks.

I think we have a good enough bandaid in place, with that arm-spe.o only
additional -I it builds on all build containers I have, the ones failing
are for unrelated reasons:
