The former is obviously a pasto. Impact: * s390_feat_bitmap_to_ascii() misidentifies S390_FEAT_PCC_CMAC_AES_256 as "pcc-cmac-eaes-256". Affects QMP commands query-cpu-definitions, query-cpu-model-expansion, query-cpu-model-baseline, query-cpu-model-comparison, and the error message when s390_realize_cpu_model() fails in check_compatibility(). * s390_cpu_list() also misidentifies it. Affects -cpu help. * s390_cpu_model_register_props() creates CPU property "pcc-cmac-eaes-256" twice. The second one fails, but the error is ignored (a later commit will change that). Results in a single property "pcc-cmac-eaes-256" with the description for S390_FEAT_PCC_CMAC_AES_256, and no property for S390_FEAT_PCC_CMAC_EAES_256. CPU properties are visible in CLI -cpu and -device, QMP & HMP device_add, QMP device-list-properties, and QOM introspection. The two features are almost always used via their group msa4. Such use is not affected by this bug. Fix by deleting the wayward 'e'.
