Vector sharing has a performance cost, so we should avoid it when we can.
I think you should bounds-check the gsi_to_irq[] references. When you finally get a machine with GSI values larger than MAX_GSI_NUM, things will start failing mysteriously as you corrupt things after the gsi_to_irq[] array. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
