2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: Avi Kivity (cherry picked from commit 8d753f369bd28fff1706ffe9fb9fea4fd88cf85b) MTRR, PAT, MCE, and MCA are all supported (to some extent) but not reported. Vista requires these features, so if userspace relies on kernel cpuid reporting, it loses support for Vista.
