Subject: [PATCH RFC 0/5] Remove some notrace RCU APIs

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

Joel Fernandes (Google) (5):
powerpc: Use regular rcu_dereference_raw API
trace: Use regular rcu_dereference_raw API
hashtable: Use the regular hlist_for_each_entry_rcu API
rculist: Remove hlist_for_each_entry_rcu_notrace since no users
rcu: Remove rcu_dereference_raw_notrace since no users
