[PATCH v5 0/7] xen/arm: move to mach-virt and support SMP

[Stefano Stabellini <stefano.stabellini@eu.citrix.com>]

Hi all,
this patch series, based on 3.9-rc3, moves xenvm to mach-virt,
introduces SMP support in Xen on ARM and implements machine reboot and
power off via Xen sched_op hypercalls.

Each patch comes with a detailed changelog.


The merge window is approaching, this patch series only contains Xen
specific changes for ARM, if anybody has any objections speak now
please.

I would like an ack from an ARM maintainer on patch #4 and #5 since they
touch generic ARM Makefiles.


Changes in v5:
- allocate xen_vcpu_info dynamically, aligning it to the size of the
struct;
- use VCPUOP_register_vcpu_info on cpu0 too;
- set pm_power_off and arm_pm_restart from the Xen specific
intialization code.
