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.

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
