This series is outside of RCU, including things like fixes for bug triggered by RCU commits. 1. Fix pr_fmt() bug for header use of printk, courtesy of Joe Perches. 2. Remove redundant INIT_TASK_RCU_TREE_PREEMPT() macro. 3. Allow migrating kthreads into online but inactive CPUs, courtesy of Tejun Heo. 4. Add expedited private command to sys_membarrier(), courtesy of Mathieu Desnoyers. Changes since v1: o Substitute Mathieu Desnoyer's expedited private command for expedited grace periods in sys_membarrier(). o Remove Wanpeng Li's fix of use of smp_processor_id() in preemptible in cputime because it is now in mainline.
