This looks fine, and I'm actually ok getting the core changes through
the arm64 branch, since this has been discussed across architectures,
and I think "whoever does the work gets to drive the car".

After all, a lot of the core changes originally came from x86 people
(pretty much all of it, historically). No reason why arm64 can't get
some of that too.

But with the glory comes the blame when something breaks ;)
