I'm finalising the arm64 queue today, so I don't really want to pull in
additional changes beyond critical fixes at this point, I'm afraid. I was
half-expecting a pull request from the riscv side last week but I didn't
see anything.
FWIW, if there's still no movement by -rc1, then I'm happy to queue all
of this on its own branch in the arm64 tree for 5.21.
Let me know.
Will
