Stop me if I'm missing something, but doesn't Scott's patch series need
yours? And if you remove the manual relocas in yours, doesn't that make
your series unable to function properly until Scott's series is applied
too?

If I am not mistaken, then maybe Scott's and your patches should be
merged in a single series, with adequate attribution of course.
