Implement support to save/restore the ARM KVM VGIC state from the kernel. The basic appraoch is to transfer state from the in-kernel VGIC to the emulated arm-gic state representation and let the standard QEMU vmstate save/restore handle saving the arm-gic state. Restore works by reversing the process. The first patches adds missing features and fixes issues with the arm-gic implementation in qemu in preparation for the actual save/restore logic. The patches depend on the device control patch series sent out earlier, which can also be found here: git://git.linaro.org/people/cdall/qemu-arm.git migration/device-ctrl-v4 The whole patch series based on top of the above can be found here: git://git.linaro.org/people/cdall/qemu-arm.git migration/vgic-v5 Changes are described in the individual patches.
