Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git...

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
