This is still a ginormous patch for something that should be simple.

I've put my patches (and a bunch on top) in:

git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git core/softirq

but got a fairly significant regression report from 0day on that, and
haven't had time/motivation to look at that.
