Here are some RCU fixes and cleanups. The main one is the TREE07 stuttering fix
which makes the test pass now. I am continuing to test these but I am sending
it out for review in advance. Thanks.

Joel Fernandes (Google) (5):
  rcutorture: Fix stuttering races and other issues
  srcu: Fix error handling in init_srcu_struct_fields()
  tree/nocb: Adjust RCU_NOCB_WAKE_* macros from weaker to stronger
  tree/nocb: Improve readability of nocb_gp_wait()
  Revert "checkpatch: Error out if deprecated RCU API used"
