Entirely unrelated to this pull request (which I already pulled and
pushed out, as noted by pr-tracker-bot), since I looked at these it
just reminded me about a question I've had for a while...

Do we have any long-term (or even short-term?) plans to just make
mglru be the one and only model?

Yes, right now it's not just a Kconfig choice, but a real technical
issue too: it depends on having enough flags available, so we have
that "cannot use it on 32-bit with sparsemem".

But I'm hoping there is a plan or a workaround for that?

Because I feel like we really don't want to keep this "two different
models" situation around forever.
