    Subject[PATCH v5 09/15] KVM: SVM: Enable SEV/SEV-ES functionality by default (when supported)
    From
    Enable the 'sev' and 'sev_es' module params by default instead of having
    them conditioned on CONFIG_AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT. The extra
    Kconfig is pointless as KVM SEV/SEV-ES support is already controlled via
    CONFIG_KVM_AMD_SEV, and CONFIG_AMD_MEM_ENCRYPT_ACTIVE_BY_DEFAULT has the
    unfortunate side effect of enabling all the SEV-ES _guest_ code due to
    it being dependent on CONFIG_AMD_MEM_ENCRYPT=y.
