Subject[PATCH 0/12] Nested SVM cleanups

here is a first round of patches to clean up the code for SVM virtualization
for KVM on AMD. There is more to clean up but since I am on vacation the rest
of the week here is what I have queued up so far. Maybe this saves me from
rebasing this code next week ;-)
I tested these patches with KVM in KVM and it works stable with and without
nested SMP. It doesn't seem to break anything.
