I do not have the time to maintain anything outside of coresight -
listing individual files as I did removes any ambiguity on that front.
I'm happy to add tools/perf/arch/arm and tools/perf/arch/arm64/ if you
agree to maintain them.  In that case you will have to be more
specific about the "other related folders" you are referring to above.
