Pull x86 cpu updates from Ingo Molnar: "Misc updates: - Extend the x86 family/model macros with a steppings dimension, because x86 life isn't complex enough and Intel uses steppings to differentiate between different CPUs. :-/ - Convert the TSC deadline timer quirks to the steppings macros. - Clean up asm mnemonics. - Fix the handling of an AMD erratum, or in other words, fix a kernel erratum" * tag 'x86-cpu-2020-06-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/cpu: Use RDRAND and RDSEED mnemonics in archrandom.h x86/cpu: Use INVPCID mnemonic in invpcid.h x86/cpu/amd: Make erratum #1054 a legacy erratum x86/apic: Convert the TSC deadline timer matching to steppings macro x86/cpu: Add a X86_MATCH_INTEL_FAM6_MODEL_STEPPINGS() macro x86/cpu: Add a steppings field to struct x86_cpu_id
