Crazy.
Yes. tl;dr I gave up after failing to unwind a header dependency chain [1]. The source of the trouble was trying to find an existing top-level header file that included an asm local version, but also needed to include mmzone.h for the definition of SUBSECTION_SIZE. include/linux/io.h fit that requirement, pulling in mmzone.h there proved more difficult than my header unwinding skills could accomplish.
