[PATCH v4 0/6] nSVM/SVM features

[Maxim Levitsky]

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,
	Maxim Levitsky
