Merge branch 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Thomas Gleixner:
- watchdog fixes for full dynticks
- improved debug output for full dynticks
- remove an obsolete full dynticks check
- two ARM SoC clocksource drivers for sharing across SoCs
- tick broadcast fix for CPU hotplug
* 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
tick: broadcast: Check broadcast mode on CPU hotplug
clocksource: arm_global_timer: Add ARM global timer support
clocksource: Add Marvell Orion SoC timer
nohz: Remove obsolete check for full dynticks CPUs to be RCU nocbs
watchdog: Boot-disable by default on full dynticks
watchdog: Rename confusing state variable
watchdog: Register / unregister watchdog kthreads on sysctl control
nohz: Warn if the machine can not perform nohz_full
