Subject: [PATCH 0/3] rcu/nocb: Fixes and simplification

Hi,

Some updates for the nocb side:

* 1st patch is a simplification on adding/deleting an rdp to a nocb group

* 2nd and 3rd are fixes for the kthread's creation failure path

Frederic Weisbecker (1):
  rcu/nocb: Add/del rdp to iterate from rcuog itself

Zqiang (2):
  rcu: Invert rcu_state.barrier_mutex VS hotplug lock locking order
  rcu/nocb: Fix NOCB kthreads spawn failure with
    rcu_nocb_rdp_deoffload() direct call
