I think it's probably fine now - you have ample justification, and you
seem to be ensuring that things are done safely.

The only thing I'm left wondering about is whether the bits outside
arch/arm should go to anyone else, but MAINTAINERS is being unhelpful
on that - so I'm tempted to say that if someone should've been copied
who hasn't, and they're not in MAINTAINERS that's their problem.
