Subject[PATCH tip/core/rcu 0/7] Real-time updates for 3.19
Hello!

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.

Thanx, Paul
