Perhaps my judgement is too colored by benchmark(et)ing, and desires to
have repeatable results on things like neperf, but I very much like to
know where my interrupts are going and don't like them moving around.
That is why I am not particularly fond of either flavor of irq balancing.
That being the case, whatever is out there aught to be able to be
disabled on a running system without having to roll bits or reboot.
