A way to disable the spinning in the core code and thus arm64 wont spin
there anymore. Good.

Spinning is bad and a waste of cpu resources. If this is done then I
would like the arch code to implement the spinning and not the core so
that there is a motivation for the arch maintainer to
come up with a way to avoid the spinning at some point.

The patch is ok as is.
