Need to revisit the sequence of operations when testing for the split lock detect feature. It is model specific, so we must check the model number before looking at CORE_CAPABILITIES.
I marked it all for stable ... some tweaking would be needed if the X86_MATCH_INTEL stuff from v5.7 doesn't get backported.
Tony Luck (3): x86/split_lock: Update to use X86_MATCH_INTEL_FAM6_MODEL() x86/split_lock: Bits in IA32_CORE_CAPABILITIES are not architectural x86/split_lock: Add Tremont family CPU models
