[PATCH]x86/cpufeatures.h: Enumerate A Few New AVX-512 Features

[Fenghua Yu]

From: Fenghua Yu <fenghua.yu@xxxxxxxxx>

A few new AVX-512 instruction groups/features are added in cpufeatures.h
for enuermation: AVX512DQ, AVX512BW, and AVX512VL.

The specification for latest AVX-512 including the features can be found at
