s390x: implement SIGP restart and shutdown
An s390x OS does reboot and shutdown triggers through hypercalls that we didn't implement on the TCG backend yet. That means that so far we couldn't shut down virtual machines for example, having them hang on shutdown when not using KVM. With this patch, this restriction is gone. We can now shut down and reboot s390x virtual machines even when using the TCG backend. Signed-off-by: Alexander Graf <agraf@suse.de>
