3.13.11.3 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Viresh Kumar <viresh.kumar@xxxxxxxxxx> commit 521c42990e9d561ed5ed9f501f07639d0512b3c9 upstream. tick_check_replacement() returns if a replacement of clock_event_device is possible or not. It does this as the first check: if (tick_check_percpu(curdev, newdev, smp_processor_id())) return false; Thats wrong. tick_check_percpu() returns true when the device is useable. Check for false instead.
