This means you have to force these drivers to be built (since this file will always be built for sharp stuff.) This doesn't seem like a good solution.

That's particularly gruesome - firstly, two statements inside a macro. Secondly, no barrier() or cpu_relax() in there (as the kernel janitors like to see.) It won't make any difference to the generated code, but makes other folk happier.
