> When initiating I/O on a multiqueue and multi-IRQ device, we may want
> to select a queue for which the response will be handled on the same
> or a nearby CPU.  This requires a reverse-map of IRQ affinity.  Add
> library functions to support a generic reverse-mapping from CPUs to
> objects with affinity and the specific case where the objects are
> IRQs.
