Thanks Rafael!

Absolutely understood on the need for Acks.

For ARM let us try a few more CCs

+CC Will, Lorenzo, Hanjun.

Also Ingo on basis of showing a passing interest in the x86 patch
previously.  Otherwise I think we have the x86 people most like to
comment already cc'd.

https://patchwork.kernel.org/cover/11174247/ has the full series.

I'd appreciate anyone who has time taking a look at these.  The
actual actions in the architectures are very simple, but I may well
be missing some subtlety.
