Ok, this thread died down without any resolution.

Are you talking about the patch that made HI_SOFTIRQ and
TASKLET_SOFTIRQ special, and had this:

  #define SOFTIRQ_NOW_MASK ((1 << HI_SOFTIRQ) | (1 << TASKLET_SOFTIRQ))

in it?

I think I'll just commit the damn thing. It's hacky, but it's simple,
and it never got applied because we had smarter suggestions. But the
smarter suggestions never ended up being applied either, so..
