Re: [PATCH tip/core/rcu 0/5] Related non-RCU updates

[Paul E. McKenney]

Hello!

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.

							Thanx, Paul
