I am very much in favour of this, so for the series:

Acked-by: Mark Rutland <mark.rutland@....com>

Is the aim to get this in for v6.15?

I believe this will permit a number of further cleanups for arm64, and
if it's possible to get this in for v6.15, it'd be a bit easier to start
preparing those for v6.16. No big problem if that's not the case.

Mark.
