Yeah, so no. This breaks what groups are. Group events _must_ be
co-scheduled. You cannot guarantee you can schedule events from another

Also, I cannot see how this can possibly work, you cannot put these
things on the same event_context.

Also, how does this work wrt cpumasks, regular events are per cpu,
uncore events are per node.

There is so much broken stuff here without explanation its not funny.

Please explain how this does not completely wreck everything?
