Overall there is roughly 5k lines of dead code in the kernel due to this. There is a quasi-separate theme, in that some of the drivers were allowing an unbind implicitly since it is enabled by default. But for core DMA infrastructure drivers, this doesn't seem useful -- so we also disable that here which allows us to delete any ".remove" functions from the drivers that would otherwise be called during the (impossible to trigger) module removal. Since ARM covers these files the best of all architectures, each file was build tested for allmodconfig on ARM, which at the same time confirms that the files are not built with "CC [M]" -- hence genuinely non-modular. My testing and the larger patch series in general has been done against the latest linux-next tree.
