Subject: [PATCH v5 0/3] cpuid: Support AVX512_4VNNIW and AVX512_4FMAPS for KVM guest
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 v5:
* divide the whole patchset into 3 parts.
* refine commit messages.
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
He Chen (3):
cpuid: cleanup cpuid_regs definitions
cpuid: Add a helper in scattered.c to return cpuid
cpuid: add AVX512_4VNNIW and AVX512_4FMAPS instructions support
