I don't think this is a userspace regression. My guess is certain 
out of tree drivers expect a static base value, based on the wording
of the commit message. Unfortunately, his is all a little bit over

wanted to report the regression as soon as I uncovered it (I'd be
lying if I said I liked reporting bugs heh).
