You've improved the init/alloc ringbuffer naming, but this one
confuses me.  stop_ringbuffers to me says we're just idling them, but
cleanup_ring_buffer actually does the unmap and free right?

If so, it looks like this will still tear things down on suspend?

Maybe it's all the refactoring making me miss it. :)
