Right, except that I really dislike it, it touches far too much code for
no particular reason.

And I really want hardirq context for perf callbacks, some code actually
relies on it (I used to have the fallback in the timer softirq and that
broke thing at some point).

So I'm really opposed to all the softirq molestation as I see no reason
to do that at all.
