Until now I addressed the review comments from the previous round. The
biggest change is patch #4 which was completly rewritten.
I understand that it would be nicer to have shadow paging working too.
But since most users will use this feature only on processors with
nested paging (only processors with nested paging support gbpages) I
don't think it should be a show-stopper. YMMV.
Anyway, I will further try to get shadow paging support running and
stable.
