IOAPIC[0]: Invalid reference to IRQ 0

I am not even sure if this is an error. I have attached the complete
boot sequence.

I think this is because io_apic_irqs is not getting initialized properly. My next patch will contain something like:

void __init setup_IO_APIC(void)
       if (acpi_ioapic)
                io_apic_irqs = ~0;      /* all IRQs go through IOAPIC */
                io_apic_irqs = ~PIC_IRQS;

which should hopefully take care of this apparently harmless message.
