Eh? You aren't doing all of them. I think we both know who did this one (with good intentions, even).

It should be fine once the bus numbering, io resources, and IO-APIC's are dealt with. The bus numbering stuff is out there, io resource stuff is an open question, and IO-APIC stuff looks uglier than sin (as usual). Basically, a good chunk of rotorooting appears to be necessary to assign deal with a number of IRQ sources large enough to make assign_irq_vector() wrap current_vector, possibly something as invasive as supporting non-unique vectors for irq_desc's.

Sounds like a conclusive answer to the TSC for me.
