Applied to kvm-x86 svm, thanks!

[1/4] KVM: SVM: Set sev->asid in sev_asid_new() instead of overloading the return

[2/4] KVM: SVM: Use unsigned integers when dealing with ASIDs
      https://github.com/kvm-x86/linux/commit/466eec4a22a7
[3/4] KVM: SVM: Add support for allowing zero SEV ASIDs
      https://github.com/kvm-x86/linux/commit/0aa6b90ef9d7
[4/4] KVM: SVM: Return -EINVAL instead of -EBUSY on attempt to re-init SEV/SEV-ES
