static_key, we do however need to hold off preemption while modifying
the preempt notifier list, otherwise a preemption could observe an
inconsistent list state.
There is no reason to have preemption disabled in the caller,
registering a preempt notifier is a purely task local affair.
Therefore move the preempt_disable into the functions and change the
callers to a preemptible context.
