For SEV-ES guests, Ensure KVM's model of EFER is up-to-date after a CR0 load, and let userspace set tracked state via KVM_SET_SREGS, relying on the vendor code to not propagate the changes to hardware (VMCB in this case). Peter, patch 02 is different than what I sent to you off list. I'm still 100% convinced that the load_pdptrs() call is flawed, but Maxim has an in-progress series that's tackling the PDPTR save/restore mess.
