This series contains RCU documentation updates: 1. Add broken-timing possibility to stallwarn.rst. 2. Improve discussion of this_cpu_ptr(), add raw_cpu_ptr(). (Not actually an RCU patch, but here it is anyway.) 3. Document self-propagating callbacks. 4. Point call_srcu() to call_rcu() for detailed memory ordering. 5. Add CONFIG_RCU_LAZY delays to call_rcu() kernel-doc header. 6. Clarify RCU_LAZY and RCU_LAZY_DEFAULT_OFF help text. 7. Remove references to old grace-period-wait primitives.
