We _really_ dont want to call it a 'PMU' but 'events coming from an event 
source'.

The reason is that a PMU is an existing term that is quite attached to a CPU - 
while many hardware events come not from a PMU. Interrupts, error conditions, 
hotplug events, etc. etc.

Furthermore, the name 'PMU' is even less correct for software events.

So lets stick with 'events' and with some container that originates them. 
(event_source) Ok?
