Oh well. I just reviewed another patch which names this register:

   MSR_MISC_FEATURE_ENABLES

and that's how it's named in this document:

http://www.intel.com/content/dam/www/public/us/en/documents/application-notes/virtualization-technology-flexmigration-application-note.pdf
 
Can Intel please get its act together and document that register proper in
the SDM?

Thanks,
