Please correct obvious coding style violations in cases like this. Of
course here it can be taken care of while committing.

I'll assume this will clarify itself with later patches: At this point it
feels wrong to lose the IO-APIC pointer in places like this, as from
domain and value alone you won't be able to reconstruct it. I.e.
I would have considered it more natural if you simply added
another function parameter.

I also wonder whether in at least some of the cases the new
struct domain * parameters of functions couldn't be const-
qualified.

In any event I'll want to have looked at more of this series to
understand whether the patch here is okay in its current form.
