Patch specific changes are tracked in the respective email with their patch. On the level of the whole series, this changed: v2: - added 'clocksource/cadence_ttc: Use enable/disable_irq'. I hope that is more appropriate to avoid races of the timer with its interrupt handler. - added 'arm: zynq: Don't use arm_global_timer with cpufreq'. In the 3.13 merge window we enabled the arm_global_timer for Zynq. That timer is clocked by the CPU clock and hence does not provide a stabl= e clocksource when cpufreq is enabled. That patch makes the selection = of the GT driver depend on !CPU_FREQ for Zynq.
