Subject: [PATCH 0/3] xen/arm: account for stolen ticks

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
