I've spent the last week looking over these and I don't see any major
functional problems so I think these are probably ready for merging. A
couple patches got into areas of the code I'm not super familiar with,
but I've also done quite a bit of testing of this series (on IVB) and
haven't run into issues, so that increases my confidence.
I think there was one incorrectly identified function parameter I called
out on one of the early scaler patches, but with a sensible parameter
rename there, you can consider these
