This is a set of patches for optional SVM nested features.
V4: rebased on top of kvm/queue + my patch series 'SVM fixes + refactoring'
and incorporated all review feedback.
This was tested with kvm unit test, running on L0,L1, and L2,
and no new failures were seen.
This time I also tested this with all new features disabled in L1,
and in L2, to avoid repeating an issue I had in nested tsc scaling.
Best regards,
