x86 does not need to offset the address. So we can skip that costing offset
searching.

I tried to start a discussion about this patch (and others), but I
don't think you responded:
http://marc.info/?l=linux-pci&m=133036414506921&w=2

this patch does reduce some not needed ops.

and it does not affects your effects, and it just make x86 not get punished.

let's let Jesse and x86 maintainers to decide if this patch is needed.

Thanks
