From 503234b3fdcaa578395c07e393ea3e5d13958824 Mon Sep 17 00:00:00 2001 From: Liran Alon Date: Fri, 14 Sep 2018 03:25:53 +0300 Subject: [PATCH] KVM: x86: Do not use kvm_x86_ops->mpx_supported() directly Commit a87036add092 ("KVM: x86: disable MPX if host did not enable MPX XSAVE features") introduced kvm_mpx_supported() to return true iff MPX is enabled in the host. However, that commit seems to have missed replacing some calls to kvm_x86_ops->mpx_supported() to kvm_mpx_supported(). Complete original commit by replacing remaining calls to kvm_mpx_supported().
