Subject: [PATCH v6 0/3] x86/kvm: 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.

BTW. sorry for sending patch so frequently, and really appreciate your
kindly review.
