I think an unprefixed global is iffy, but I'm not going to insist on
semi-cosmetics.

The one thing I expected people to complain about is the location of
the struct. The mm_init.c file was the least bad choice I found, but
maybe something else is preferred?
I'm just trying to avoid sending V3 for this patch after someone
claims dummy ops should land elsewhere. ;)
