3.13.11.3 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Thomas Gleixner <tglx@xxxxxxxxxxxxx> commit ffde1de64012c406dfdda8690918248b472f24e4 upstream. To support the affinity setting of per cpu timers in the early startup of a not yet online cpu, implement the force logic, which disables the cpu online check. Tagged for stable to allow a simple fix of the affected SoC clock event drivers.
