I'm confused as to why you aren't allowing userspace to set/get this
MSR? Wouldn't it be needed for save/restore?
I don't see any benefit from actually exporting that MSR atm. KVM does
never read it and it'd just add additional overhead on every userspace
transition, as it'd need to be synced every time.
Save and restore?
