Do you think this patch is something you could queue on some
tip branch for v6.16?

I don't know if either arm64 or arm32 is going anywhere with
generic entry for v6.16, but having this in-tree makes it easier
to split the task going forward. We can always pull it into some
branch or just wait for v6.16-rc1 to get this patch under our
patch stacks.
