The series removes users of the following APIs, and the APIs themselves, since
the regular non - _notrace variants don't do any tracing anyway.
 * hlist_for_each_entry_rcu_notrace
 * rcu_dereference_raw_notrace

I guess the difference between the _raw_notrace and just _raw variants
is that _notrace ones do a rcu_check_sparse(). Don't we want to keep
that check?
