Ok, nice!

I'll leave that up to Thomas and Maciej to decide, they should have the
best idea of why the x86 pci-irq code looks the way it does today and
what the possible risk with my patch is.
As I said before, I still think we should also merge the 8139 driver patch,
probably without that loop. It's not great, but I'm much more confident
I understand what that does and that the patched version is better than
the current code.
