We had three queues. We are down to two and I think this is a good
thing. We only deal with FULL_NOHZ in hardirq context (looking at
v4.0-RT). Before that (FULL_NOHZ) everything was handled in softirq and
nobody was concerned (saw a problem).

It would be good if we would address a regression or a bug or something
like that.
