Subject: [PATCH 0/2] KVM: SVM: Fix SEV-ES intrahost migration

Fix two fatal bugs in SEV-ES intrahost migration, found by running
sev_migrate_tests (:shocked-pikachu:).

IIRC, for some reason our platforms haven't played nice with SEV-ES on
upstream kernels for a while, i.e. the test hasn't been run as part of my
usual testing. 

Sean Christopherson (2):
  KVM: SVM: Get source vCPUs from source VM for SEV-ES intrahost
    migration
  KVM: SVM: Skip VMSA init in sev_es_init_vmcb() if pointer is NULL
