rcu: Wire up RCU_BOOST_PRIO for rcutree
RCU boost threads start life at RCU_BOOST_PRIO, while others remain at RCU_KTHREAD_PRIO. While here, change thread names to match other kthreads, and adjust rcu_yield() to not override the priority set by the user. This last change sets the stage for runtime changes to priority in the -rt tree. Signed-off-by: Mike Galbraith <efault@gmx.de> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
