This series contains real-time-related updates: 1. Move RCU_NOCB_CPU to choice, courtesy of Stefan Hengelein. 2. Place RCU_BOOST-specific variables under pre-existing #ifdef. 3. Prevent synchronize_sched_expedited() from sending IPIs to idle and to nohz_full CPUs. 4. Unify boost and kthread priorities, and allow this unified priority to be set at boot time, courtesy of Clark Williams. 5. Remove redundant TREE_PREEMPT_RCU Kconfig option, courtesy of Pranith Kumar. 6. Handle the possibility of a no-CBs CPU posting callbacks on their last pass through the idle loop by waking up the leader kthread after the CPU has gone completely offline. 7. Fix rcuo online-time-creation reoganization bug, which seems to be a latent bug due to systems (wisely) bringing CPUs online in numerical order.
