Hi all,
this small patch series introduces stolen ticks accounting for Xen on
ARM. Stolen ticks are clocksource ticks that have been "stolen" from the
cpu, typically because Linux is running in a virtual machine and the
vcpu has been descheduled.


Stefano Stabellini (3):
      arm_arch_timer: introduce arch_timer_stolen_ticks
      xen: move do_stolen_accounting to drivers/xen/time.c
      xen/arm: account for stolen ticks
