Jiri Denemark (8):
cpu_map: Disable cpu64-rhel* for host-model and baseline
cputest: Drop some old artificial baseline tests
cputest: Give better names to baseline tests
cputest: Add some real world baseline tests
cpu_x86: Consolidate signature match in x86DecodeUseCandidate
cpu_x86: Refactor feature list comparison in x86DecodeUseCandidate
cpu_x86: Penalize disabled features when computing CPU model
cpu_x86: Ignore enabled features for input models in
x86DecodeUseCandidate
