Ah yes, I also saw that, I was hoping you would give me today to run
through my test builds.

That will do as a quick fix (Linus, can you take it now ?), however..

Yes, Grant, you should move that to a different (generic) debugfs file,
the mapping information is valuable debug data for all architectures
that use the remapper, not just powerpc and it's not an ABI (no tool I
know of rely on the location of that debugfs file) so feel free to move
it around.
Cheers,
Ben.
