I revised this series and rebased on top of Linus' tree. 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 stable
   clocksource when cpufreq is enabled. That patch makes the selection of
   the GT driver depend on !CPU_FREQ for Zynq.
