Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu-feature updates from Ingo Molnar: - Rework the Intel model names symbols/macros, which were decades of ad-hoc extensions and added random noise. It's now a coherent, easy to follow nomenclature. - Add new Intel CPU model IDs: - "Tiger Lake" desktop and mobile models - "Elkhart Lake" model ID - and the "Lightning Mountain" variant of Airmont, plus support code - Add the new AVX512_VP2INTERSECT instruction to cpufeatures - Remove Intel MPX user-visible APIs and the self-tests, because the toolchain (gcc) is not supporting it going forward. This is the first, lowest-risk phase of MPX removal. - Remove X86_FEATURE_MFENCE_RDTSC - Various smaller cleanups and fixes * 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (25 commits) x86/cpu: Update init data for new Airmont CPU model x86/cpu: Add new Airmont variant to Intel family x86/cpu: Add Elkhart Lake to Intel family x86/cpu: Add Tiger Lake to Intel family x86: Correct misc typos x86/intel: Add common OPTDIFFs x86/intel: Aggregate microserver naming x86/intel: Aggregate big core graphics naming x86/intel: Aggregate big core mobile naming x86/intel: Aggregate big core client naming x86/cpufeature: Explain the macro duplication x86/ftrace: Remove mcount() declaration x86/PCI: Remove superfluous returns from void functions x86/msr-index: Move AMD MSRs where they belong x86/cpu: Use constant definitions for CPU models lib: Remove redundant ftrace flag removal x86/crash: Remove unnecessary comparison x86/bitops: Use __builtin_constant_p() directly instead of IS_IMMEDIATE() x86: Remove X86_FEATURE_MFENCE_RDTSC x86/mpx: Remove MPX APIs ...
