Edward O'Callaghan has uploaded this change for review.
programmer: Drop dead fallback_map() boilerplate
The fallback_{un}map() boilerplate code doesn't do anything,
merly distracts away from otherwise linear control flow. Just
drop it as anything in the future that could need such a thing
is free to implement it when required.
