    objects

Denis Arefev (1):
  srcu: Fix srcu_struct node grpmask overflow on 64-bit systems

Frederic Weisbecker (8):
  rcu: Use rcu_segcblist_segempty() instead of open coding it
  rcu: Assume IRQS disabled from rcu_report_dead()
  rcu: Assume rcu_report_dead() is always called locally
  rcu: Conditionally build CPU-hotplug teardown callbacks
  rcu: Standardize explicit CPU-hotplug calls
  rcu: Comment why callbacks migration can't wait for CPUHP_RCUTREE_PREP
  srcu: Fix callbacks acceleration mishandling
  srcu: Only accelerate on enqueue time

Joel Fernandes (Google) (3):
  Revert "checkpatch: Error out if deprecated RCU API used"
  srcu: Fix error handling in init_srcu_struct_fields()
  rcu/tree: Remove superfluous return from void call_rcu* functions

Paul E. McKenney (2):
  rcu: Add sysfs to provide throttled access to rcu_barrier()
  rcu: Eliminate rcu_gp_slow_unregister() false positive
