(Add linux-arch in Cc list)

Architecture maintainers, this patch is about strengthening our memory
model a little bit, your inputs (confirmation, ack/nack, etc.) are
appreciated.

Hi Boqun,

I don't feel like I'm really qualified to give an ack here, you and the
other memory model folk know this stuff much better than me.

But I have reviewed it and it matches my understanding of how our
barriers work, so it looks OK to me.
