I ran into a warning message during randconfig testing and spent way too much time figuring out how to best address it. One thing led to another and I ended up with a 5 patch series.
Unforunately I screwed up the first version of the series and had to replace the first patch, but the second version should be much better. Please have a look at the first patch separately, it might fix an important bug and need backporting to stable kernels, or it might only address a harmless warning. For the rest of the patches, please merge for 4.13 unless you see something wrong.
