This regression is still present in 4.15-rc9. It's been ongoing since
3.16. Could someone take a look so it can finally be fixed?

I've been trying to adapt the three patches I originally identified from
Yinghailu's for-pci-v4.1-rc8 branch onto the current mainline, and
linux-next,  but he did a forced rebase and the branch commits changed
with some being removed.
