[PATCH v4 0/2] cpuid: Support AVX512_4VNNIW and AVX512_4FMAPS for KVM guest

[He Chen]

This patch series is going to add two new AVX512 features to KVM guest.
Since these two features are defined as scattered features in kernel,
some extra modification in kernel is included.

---
Changes in v4:
* divide patch into 2 parts, including modification in scattered.c and
  support new AVX512 instructions for KVM.
* coding style.
* refine commit message.

Changes in v3:
* add a helper in scattered.c to get scattered leaf.

Changes in v2:
* add new macros for new AVX512 scattered features.
* add a cpuid_count_edx function to processor.h
