[PULL 08/19] sev/i386: Enable an SEV-ES guest based on SEV policy

Posted by Paolo Bonzini 4 years, 10 months ago

From: Tom Lendacky <thomas.lendacky@amd.com>

Update the sev_es_enabled() function return value to be based on the SEV
policy that has been specified. SEV-ES is enabled if SEV is enabled and
the SEV-ES policy bit is set in the policy object.
