Thanks David. What was the verdict? (for the public record). If we need to
get a change into upstream, let's get that teed up before 4.12 merge.

And for other folks following along with this thread: I'm not just picking
on Cavium here. I'll be doing the same with *every* ARM server SoC company
as necessary over the coming months. We are going to have militantly
compliant standards adherence in this industry and every ARM server SoC is
going to "just work" with an upstream Linux kernel with an ACPI enabled
platform. This will be so utterly clean and boring it'll be amazing.

Jon.
