I've given these a spin on Juno R1, which now boots happily. FWIW, I also did a test-merge with the arm64 for-next/core branch, which git was able to figure it out automatically. The result builds cleanly and boots without issue on Juno R1. Catalin/Will, assuming there are no further gotchas, are you happy for the arm64 patch to go via the tip tree? Thanks, Mark.
