Someone else inside your organization? If nobody is available, then so
be it, let that be clear in the JSON file (see below) and then I
wouldn't be waiting for acks/reviewed-by messages for such cases.

I think this should be the case, would you be willing to add a note to
that effect at the top of the JSON files?

And an extra note at tools/perf/pmu-events/README telling users to look
at the json files to figure out what Reviewed-by tags are required for
something to get merged? One extra Reviewed-by would be ok? Who would be
the reviewers for each arch? Would that be at the top of the JSON file?
