I can't quote your patch due to the way it is included in the message 
(inline text after the signature).

What's unclear based on the documentation if the address has to fall in 
the range covered by the link map (i.e., if there are indeed only three 
cases, or five).  If there is indeed a precondition that the address is 
in some special range, you should add it to the comment.

There is also a stray comment in the function itself.

I expect unit tests which look like this to be noncontroversial.

Things are more interesting if you have to add testing hooks to the 
code, or export additional symbols.

Thanks,
Florian
