xen/arm: move to mach-virt and support SMP

xen/arm: move to mach-virt and support SMP

[Stefano Stabellini]

Hi all,
this patch series, based on 3.9-rc3, moves xenvm to mach-virt and
implements SMP support in Xen on ARM.


Stefano Stabellini (4):
      xen/arm: implement HYPERVISOR_vcpu_op
      xen/arm: SMP support
      xen: move the xenvm machine to mach-virt
      xenvm: add a simple PSCI node and a second cpu

[PATCH 2/4] xen/arm: SMP support

[Stefano Stabellini]

Map vcpu_info using VCPUOP_register_vcpu_info on secondary cpus.

Call enable_percpu_irq on every cpu.

Actually pass a percpu variable to request_percpu_irq.
