Yes, we should in general try moving all test modules out of the core.

If you're working on this please make sure to take a look at how the
various automated testing systems cope with modules built under
selftests (personally I think everything I care about uses tuxmake
builds, but there's other stuff out there).  I think the answer for a
bunch of them right now is badly, but I didn't actually go check.

There is huge discussion in the past on converting test modules into
kunit modules [1]. Selftests is not a correct place to keep kernel modules.

I don't care where we move them, but mm/ and lib/ is *certainly not* the right
place for MM specific test modules.

Anyhow, I think converting stuff to kunit makes sense. I am not sure if that is
really applicable to e.g., gup_tests though.
