This results in a flat list of subclasses including aliases, to be refined later. Move cpu_ppc_init() to translate_init.c and drop helper.c. Long-term the idea is to turn translate_init.c into a standalone cpu.c. Inline cpu_ppc_usable() into type registration. Split cpu_ppc_register() in two by code movement into the initfn and by turning the remaining part into a realizefn. Move qemu_init_vcpu() call into the new realizefn and adapt create_ppc_opcodes() to return an Error. Change ppc_find_by_pvr() -> ppc_cpu_class_by_pvr(). Change ppc_find_by_name() -> ppc_cpu_class_by_name(). Turn -cpu host into its own subclass. This requires to move the kvm_enabled() check in ppc_cpu_class_by_name() to avoid the class being found via the normal name lookup in the !kvm_enabled() case. Turn kvmppc_host_cpu_def() into the class_init and add an initfn that asserts KVM is in fact enabled. Implement -cpu ? and the QMP equivalent in terms of subclasses. This newly exposes -cpu host to the user, ordered last for -cpu ?.
