Like Keith, I'd like to keep the amount of decoding in the kernel as
minimal as possible. We already have si_isr in the siginfo structure,
so apps/libraries can decode things themselves. Having said that, we
ought to decode things sufficiently so that si_code can be set to the
correct value (where this makes sense). Hopefully, that won't add
tons of code and it would help application portability.
