472 * A support function for a PIC to decide if provided ISRC should be inited
473 * on given cpu. The logic of INTR_ISRCF_BOUND flag and isrc_cpu member of
474 * struct intr_irqsrc is the following:
475 *
476 * If INTR_ISRCF_BOUND is set, the ISRC should be inited only on cpus
477 * set in isrc_cpu. If not, the ISRC should be inited on every cpu and
478 * isrc_cpu is kept consistent with it. Thus isrc_cpu is always correct.
