Hi Hendrik, Thomas,

I noticed that in 4.17-rc1 support was included for s390 perf 
pmu-events. I also notice that the JSONs contain many common (identical 
actually) events between different chips for this arch.

Support was added for factoring out common arch events in 
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/tools/perf/pmu-events?h=next-20180420&id=e9d32c1bf0cd7a98358ec4aa1625bf2b3459b9ac

ARM64 chips use this feature. I am not familiar with the s390 arch, but 
do you think you could also use this feature?

Thanks,
John
