I don't like exporting low-level implementation details like this, and
it seems a bit bogus to have an SLB miss handler in a module. Could
you move the SLB miss handler to the non-modular part?

Yes. The series already has the patches to move the SLB miss handler
into the built-in parts. At the moment, we also need the symbols for
the context switch code that also touches the SLB entries. We already
have a patch to move that as well, but are still discussing the details
of that.

I'll follow up with a patch to replace this one.
