[PATCH 0/3] KVM: SVM: SEV{-ES} bug fixes

[Sean Christopherson]

Misc bug fixes in SEV/SEV-ES to protect against a malicious userspace.
All found by inspection, I didn't actually crash the host to to prove that
userspace could hose the kernel in any of these cases.  Boot tested an SEV
guest, though the SEV-ES side of patch 2 is essentially untested as I
don't have an SEV-ES setup at this time.

Sean Christopherson (3):
  KVM: SVM: Use online_vcpus, not created_vcpus, to iterate over vCPUs
  KVM: SVM: Do not set sev->es_active until KVM_SEV_ES_INIT completes
  KVM: SVM: Do not allow SEV/SEV-ES initialization after vCPUs are
    created
