My understanding is that smp_write_intsrc() uses relative offsets from the APIC. So to get the interrupt number, you add the number of interrupts from each APIC up to m->apicid_8132_2, + 0. There's probably a better explanation on the list somewhere, but I couldn't find it right now. Hopefully it's enough to get you started.
