[PATCH 0/3] Split lock enumeration cleanup and fixes

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
