You can do it today by temporarily replacing the policy in current. It's somewhat
ugly. Interrupts don't use the policy, so it's not racy.

But yes if it's common it would seem reasonable to have a cleaner function for it,
if you have a clear use case and you can do it without impacting the page allocator fast path.
