You'll have to confirm in your kernel build directory and .config
that you really don't have these modules enabled.

Since there's no kernel recipe that I've seen that builds all modules,
they just the modules specified in your .config are built and packaged
by the kernel classes.

But maybe I've misunderstood the question, or what you are seeing.
