Subject: [PATCH v2 0/6] nSVM optional features

This is a resend of a few patches that implement few
SVM's optional features for nesting.

I was testing these patches during last few weeks with various nested configurations
and I was unable to find any issues.

I also implemented support for nested vGIF in the last patch.

Best regards,
	Maxim Levitsky
