Although the "Intel Virtualization Technology FlexMigration
Application Note" (http://www.intel.com/Assets/PDF/manual/323850.pdf)
does not document support for extended model 2H model DH (Intel Xeon
Processor E5 Family), empirical evidence shows that the same MSR
addresses can be used for cpuid masking as exdended model 2H model AH
(Intel Xen Processor E3-1200 Family).
