Can you clarify the question? I've been waiting for v2.

I think you said that this will remain arm64 specific and the existing
generic kasan_populate_early_shadow() doesn't work.

If there's nothing else that needs resolving, please go ahead and send
v2 (the __weak comment still needs resolving).

Thanks,
