For reference, here is the full list of functions that use FeatureWordInfo::feat_names: * x86_cpu_get_migratable_flags(): not affected, as it just check for non-NULL values. * report_unavailable_features(): informative only. It will start printing feature names with hyphens. * x86_cpu_list(): informative only. It will start printing feature names with hyphens * x86_cpu_register_feature_bit_props(): not affected, as it was already calling feat2prop(). Now we can remove the feat2prop() calls safely. So, the only user-visible effect of this patch are the new names being used in help and error messages for users.
