I guess next up would be to split up i915_drv.h and intel_drv.h and see how much our driver is a spaghetti mess where everything needs everything else :-)

In general this got me wondering how self-contained the header files really need to be. Turns out even <linux/kernel.h> isn't self-contained, it fails on do_div() for my config if <asm/div64.h> isn't included some other route. Didn't dig deep, but by the looks of it this is not a new breakage (if you can call it that).
