Ok, never mind my comment on the do_IRQ() detail, this looks good after all,
you just consolidated what is there already in essence.
Pulled into tip/x86/apic [which had dependencies here], thanks Jeremy!
Btw., please remove leftover bits like:
+ //printk("cpu %d handling irq %d\n", smp_processor_id(), info->irq);
Ingo
