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
