It might be better to split this patch into two parts.

- Just the place where we do IBPB barrier for VMX/SVM
- The msr get/set handling to comprehend guest, nested support etc.

The first part should be trivial so it can possibly make it into
tip/x86/pti branch sooner, while we rework the feedback to 
address this completely. 


Cheers,
Ashok
