See commit b119fa61d440 ("locking/mcs: Order the header files in Kbuild
of each architecture in alphabetical order")

That script is a little buggy, but should work in the current case. So
first do something like:

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

Then run that script.

IIRC the bug was where a single line contained multiple headers and/or a
continuation. I should have a better version somewhere, but this one was
easier to find.
