I think this the wrong way of thinking.  In general we should always
avoid including asm/ headers unless there is no other way.  No other
way is not formalized right now, but I think the answer is roughly if
no linux/ headers includes that asm header.  This will probably give
a few wrong results at the moment, but it's probably worth fixing
them up.
