Ah yes! my bad. _force_ doesn't check the mask against the online CPUs.
Hmm, I didn't realize that you also added irq_set_affinity_and_hint()
in your last patchset.

I did not. It just exposed irq_set_affinity().

See https://lore.kernel.org/r/87wnrs9tvp.ffs@nanos.tec.linutronix.de (local)
for the new hint interface I came up with.
