ARM64 is going to use it for haltpoll support (for poll-state)
so move the definition to be arch-agnostic and allow architectures
to override it.
This says that the definition is moved.

But the definion is only added here.
I would expect that the patch also removes the original definion.
Thanks for catching this. I updated the patch:
