Some loads cannot tolerate the jitter induced by all softirqs being processed
at the same priority.  Let the user prioritize them again.

I'm going to postpone this. While it might make sense in general I'm
going to wait for tglx, Steven and others to see if this is what we want
or if there are some plans redoing the softirq handling.
