This may not even be needed, i.e. Sebastian Siewior said that recent
rt patches already identify the way this driver uses threaded interrupts
and automagically does the right thing, Sebastian?

He mentioned this in this message:

But I replied to Mike and don't recall getting an answer to my last
question.

Meanwhile a kernel with these two patches survived the original bug
reported at Red Hat's bugzilla.
