From 2896ba40d0becdb72b45f096cad70633abc014f6 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Tue, 3 Sep 2019 15:15:44 +0200 Subject: iommu: Don't use sme_active() in generic code Switch to the generic function mem_encrypt_active() because sme_active() is x86 specific and can't be called from generic code on other platforms than x86.
