kernel.h elimination (in the form it exists right now) is very fruitful.
However, you may help with the (say) ioctl.h or whatever you consider
really fruitful, we all will thank you (no jokes).

This is the first #include path for ioctl.h

Get past that and sched.h => processor.h => cpuid/api.h also
gets you to paravirt.h.
I suspect a lot of headers get pulled in like that.
