3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: John Stultz <[email protected]> commit aac74dc495456412c4130a1167ce4beb6c1f0b38 upstream. After learning we'll need some sort of deferred printk functionality in the timekeeping core, Peter suggested we rename the printk_sched function so it can be reused by needed subsystems. This only changes the function name. No logic changes.
