x86/io_apic: Reevaluate vector configuration on activate()
This changes factors out the code that accesses the chip data, but at
the same time limits this to only do this for the ioapic chip:
static void ioapic_configure_entry(struct irq_data *irqd)
+{
+ struct mp_chip_data *mpd = irqd->chip_data;
+ struct irq_cfg *cfg = irqd_cfg(irqd);
+ struct irq_pin_list *entry;
+
+ /*
+ * Only update when the parent is the vector domain, don't touch it
+ * if the parent is the remapping domain. Check the installed
+ * ioapic chip to verify that.
+ */
+ if (irqd->chip == &ioapic_chip) {
+ mpd->entry.dest = cfg->dest_apicid;
+ mpd->entry.vector = cfg->vector;
+ }
