The only "interesting" fix is ensuring that writeable, shared mappings are initially mapped as clean since we inadvertently broke the logic back in v4.14 and then noticed the problem via code inspection the other day. The only critical issue we have outstanding is a sporadic NULL dereference in the scheduler, which doesn't appear to be arm64-specific and PeterZ is tearing his hair out over it at the moment.
