Hmm, I just see the module macros in the code, since it's a bool Kconfig
I think the dump_pagetables.c need a cleanup,
remove the #include <linux/module.h> and below lines:
MODULE_LICENSE("GPL");
MODULE_AUTHOR("Arjan van de Ven <arjan-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>");
MODULE_DESCRIPTION("Kernel debugging helper that dumps pagetables");

I think not necessary limit to efi=? Probably something like ptdump_dmesg=1|0
