[PATCH 0/2] KVM: x86: Fixes for SEV-ES state tracking

[Sean Christopherson]

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.
