This patch enables the ability to launch the VMM on AMD on a single core. It uses an old hack to deal with a lack of our own CR3, which will be removed once we have the CR3 part added, and as a result, it only works on single core. It also cannot be stopped, as that logic is really specific to the way that the VMM was launched which will change once all of this code is moved to C++, so that functionality will come later as well.
