It's not just a a "helper", it is internal magic for KASAN and low-level
code patching.  No driver has any business checking if something is a
module text/data address, and I'm fairly sure how they are using it is
actually wrong if DM is built in.

FYI, I also agree that the concept is a disaster as well.
