[PATCH] Update AMD SVM feature flags

[PATCH] Update AMD SVM feature flags

[Wei Huang]

[-- Attachment #1: Type: text/plain, Size: 242 bytes --]

This patch updates AMD SVM feature flags (0x8000000A:EDX). It adds 
several new feature bits, along with feature description. The feature 
names are changed to be consistent with Linux kernel.
