So what I did was something like:

for i in arch/*/include/asm/Kbuild
do
	echo "generic-y += preempt.h" >> $i
done

Whoever is going to hand edit all gazillion archs for changes like that?
And sort(1) is annoying in that it doesn't do in-place sort; you'll end
up with empty files if you try the naive thing.

Worse most of those Kbuild files include other random garbage, which
makes automated sorting harder still.

So unless there's a sane and easy way to keep it sorted; I'm going to
ignore that rule.
