Patch 1 implements AMD semantics for non-leaf PDPEs and PML4Es, which are a bit different from Intel. The SVM test relies on this, so fix it.
Patch 2 lets nested SVM implement nested page fault correctly. We were not setting bits 32/33. Patches 3 and 4 fix the interaction between emulator and nested EPT/NPT, which was reported by Valentine. Reviews are very welcome, I'm walking on thin ice here...
