I think that's caused by the conflicts between the arm64 and the mm
trees Stephen reported earlier. They are non-trivial and likely
something got wrong in the conflict resolution (my fault for not
checking before pushing the branch, not blaming Stephen ;)).

I dropped the conflicting patches from the arm64 tree.

Thanks.
