I think that Michael is OK with standardizing these resources, but he is
not really happy with the term "doorbell".

From the one hand, using the term "XXX notification" would be more
consistent with the virtio spec, since virtio already uses the term
"notification" for driver-to-device signaling regarding the virtqueues.

On the other hand, I can't find something for XXX that would sound
better than "doorbell".

But let's see what Michael has to say.
