Don't think we have any, however the usage is straightforward: This is a
bitmask describing the CPUs on which Xenomai threads and IRQs that will
be created in the future shall be bound to. Just set it before firing up

BTW, I found a hint on an "IRQ19 issue" in my archive, but I still need
to interview my colleague on details.
