Hi,

Here is a bunch of accumulated cleanups. Many of them are trivial but
beware some tricky ordering changes in the middle :-)

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	rcu/dev

HEAD: 43d6b973aeb7459d29cd52054142291b099bf8ad

Thanks,
	Frederic

Frederic Weisbecker (10):
      rcu: Use rcu_segcblist_segempty() instead of open coding it
      rcu: Rename jiffies_till_flush to jiffies_lazy_flush
      rcu/nocb: Remove needless LOAD-ACQUIRE
      rcu/nocb: Remove needless full barrier after callback advancing
      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: Remove references to rcu_migrate_callbacks() from diagrams
      rcu: Comment why callbacks migration can't wait for CPUHP_RCUTREE_PREP
