Note that I'm not acking nor nacking the patch; I'm not involved with
the RT stuff and I've never looked at the code, so I don't know what
the implications of the patch itself are.

I've merely explained the point of the simple irq handler.

Maybe the simple irq handler should never have been something that got
sucked into the generic IRQ stuff, but kept as something specific to
Neponset.
