Yes, I had thought about that as well. We certainly need to go this route
if we are building multiple mach types at the same time. Fortunately the
vast majority of mach types do not have their own include structure, so
it's not been something that's popped up yet as a real problem.

This was before I realized that asm-offsets.h was being placed in
include/asm-sh anyways, despite the directory not existing until Kbuild
created it. I don't have any problems with moving it back, I just thought
the idea of multiple include directories for the same asm/ prefix seemed
non-intuitive.
