That's unique enough that it can be left as-is I think, rather than
having to add that special knowledge into the macro.

A solution to this would be to alias (using .equ) the feroceon_xxx
functions to feroceon_range_xxx, and then use the standard
define_cache_functions macro, which would be more in keeping with
the way these things are supposed to work.
