With those two changes in place, we no longer need the fake
pci_sys_data/pci_bus structures for faking config space writes,
and the stack usage goes down as well.

I'm ATM unable to test this change, but will do that at some point.
Meanwhile, I guess there is nothing I can say against this patch.
Thanks.

Thanks! I've queued it up in next/fixes-non-critical for linux-4.4
now, if you find something wrong later, we can revert or fix up.

There is no urgency for this one, especially since you still want to
test it, so no reason to put it in 4.3.

This was the last pre-2015 build warning for the ARM defconfigs
and allmodconfig, all remaining warnings are regressions or new
code, and I've submitted patches for those. Let's see if we can
get to a warning-free kernel build in 4.4.
