Well it would need to work.

Also I personally didn't see the point of the irq items list because
there's no good way to dynamically allocate it in a NMI, so the window
would be always "fixed size" anyways and you could as well just use 
per cpu data.

That's why for simple self irq I preferred Ying's original patch.
