Currently the MSM timers use the same physical counter for the clockevent and clocksource. This works as long as the clocksource isn't stopped from ticking during normal operation but unfortunately that isn't the case and the clocksource is stopped when the clockevent is shutdown. Even worse, switching the clocksource via sysfs at runtime will hang the system. This series reorganizes the MSM timer code so that one counter is only used for either a clocksource or a clockevent, and not both. In the process we reduce the lines of code and fix a few long-standing bugs. I plan to add sched_clock support on top of this series once the ARM generic patches are posted again (hopefully next week).
