I have tentatively applied these to pci/resource for v5.6, but I need
some kind of high-level description for why we want these changes.
The commit logs describe what the code does, and that's good, but we
really need a little more of the *why* and what the user-visible
benefit is. I know some of this was in earlier postings, but it seems
to have gotten lost along the way.
