Sounds reasonable, but no answers yet.

Can you take at least patch 1 and 2 meanwhile, preferably 6 and 7 (the
ARM parts) also if you are OK with it?
I have other patches that depend on 1/7 and 2/7, so having them upstream
would help me and reduce further dependency churn.
I am happy to resend the remaining patches for further discussion later.
