No worries, yes we need to understand how to sync the changes, as I said it is probably better for my series to be dropped, posted at v4.13-rc1, create a branch out of it and ask all PCI host bridges to be based against it, it is up to Bjorn to decide what's the least complicated way for him to sync all these changes.
