| From | Brijesh Singh <> | Subject | [RFC Part1 PATCH v3 07/17] x86/mm: Include SEV for encryption memory attribute changes | Date | Mon, 24 Jul 2017 14:07:47 -0500 |

From: Tom Lendacky <thomas.lendacky@amd.com>
The current code checks only for sme_active() when determining whether to perform the encryption attribute change. Include sev_active() in this check so that memory attribute changes can occur under SME and SEV.
