The name of the ring still implies it is used only for memory accesses,
which is no longer the case. It is also used to deliver variuos HVM events,
thus the name monitor is more appropriate in this setting.

I agree with Julien below, this should probably be put into the p2m layer.
The ARM definition of the function could then simply be an inline
definition that just returns 0.

Did you look at the resulting patch to see what happened? It didn't
remove the mem_event stuff, but adjusted it enough to become the
vm_event one while removing the previously added vm_event part
again. Another argument against this approach imo.
