Hi,

this is the second and extended version of my patchset to clean up the code for
SVM virtualization in KVM. The patchset was tested with KVM on KVM and showed
no regressions. It was tested with Nested Paging and with Shadow Paging on the
first-level guest. 
As a major change this patchset enables the nested SVM code by
default. It is still required to start qemu with -enable-nesting,
though.

Changes to the previous version:

	* added Acked-by tags
	* added missing patch descriptions
	* addressed review comments
	* dropped dynamic debugging patch (will be replaced by change
	  to tracing infrastructure)
	* dropped patch moving nested #pf handling because it broke
	  nested SVM with shadow paging
	* added more cleanups (e.g. removed nested_svm_do and
	  function pointer code flow)
	* fixed 2 minor issues
	* enabled nested svm by default

Thanks,

	Joerg
