Merge tag '3.9-rc3-smp-6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/sstabellini/xen 

Pull ARM Xen SMP updates from Stefano Stabellini:
 "This contains a bunch of Xen/ARM specific changes, including some
  fixes, SMP support for Xen on ARM, and moving the xenvm machine from
  mach-vexpress to mach-virt.

  The non-Xen files that are touched are arch/arm/Kconfig, to select
  ARM_PSCI on XEN, and arch/arm/boot/dts/Makefile, to build the xenvm
  DTB if CONFIG_ARCH_VIRT.

  Highlights:

   - Move xenvm to mach-virt.

   - Implement SMP support in Xen on ARM.

   - Add support for machine reboot and power off via Xen hypercalls"

* tag '3.9-rc3-smp-6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/sstabellini/xen:
  xen/arm: remove duplicated include from enlighten.c
  xen/arm: use sched_op hypercalls for machine reboot and power off
  xenvm: add a simple PSCI node and a second cpu
  xen/arm: XEN selects ARM_PSCI
  xen: move the xenvm machine to mach-virt
  xen/arm: SMP support
  xen/arm: implement HYPERVISOR_vcpu_op
  xen/arm: actually pass a non-NULL percpu pointer to request_percpu_irq
