Subject: [PATCH RT v3 0/5] RCU fixes

With these patches, rcutorture works on PREEMPT_RT_FULL.

Scott Wood (5):
  rcu: Acquire RCU lock when disabling BHs
  sched: Rename sleeping_lock to rt_invol_sleep
  sched: migrate_dis/enable: Use rt_invol_sleep
  rcu: Disable use_softirq on PREEMPT_RT
  rcutorture: Avoid problematic critical section nesting
