Herne" , Cornelia Huck , Paolo Bonzini , Richard Henderson , Andreas Faerber , Michael Mueller This patch implements routine s390_cpu_model_init(). It is called by the realize function during instantiation of an cpu object. Its task is to initialize the current accelerator with the properties of the selected processor model.
