3.11.10.15 -stable review patch. If anyone has any objections, please let me know.
------------------
From: John Stultz <john.stultz@xxxxxxxxxx>
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.
