Subject: [PATCH 0/2] KVM: SEV: Allow for mirroring of SEV-ES VMs

To mirror SEV-ES VMs the mirror VM needs to call LAUNCH_UPDATE_VMSA
before the original VM runs LAUNCH_FINISH. This allows the mirror's
vCPUs to be encrypted into the SEV-ES guests context and measured into
the launch digest.

Peter Gonda (2):
  KVM: SEV: Update svm_vm_copy_asid_from for SEV-ES
  KVM: SEV: Allow launch vmsa from mirror VM
