   # HEAD: 0cc5359d8fd45bc410906e009117e78e2b5b2322 x86/cpu: Update init data for new Airmont CPU model

The changes in this cycle were:

 - 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.

 Thanks,

	Ingo
