Hello! This series has miscellaneous fixes: 1. Remove extraneous parentheses from srcu_read_lock() etc.. 2. Remove RCU_NONIDLE(), courtesy of Peter Zijlstra. 3. Check callback-invocation time limit for rcuc kthreads. 4. Employ jiffies-based backstop to callback time limit. 5. Mark additional concurrent load from ->cpu_no_qs.b.exp. 6. Mark rcu_cpu_kthread() accesses to ->rcu_cpu_has_work. 7. Make rcu_cpu_starting() rely on interrupts being disabled. 8. rcu-tasks: Stop rcu_tasks_invoke_cbs() from using never-onlined CPUs. This would normally be in the rcu-tasks category, but its change to RCU's CPU-hotplug logic results in a source-code dependency that puts it here in order to avoid a merge conflict.
