From 7efb4d8a392a18e37fcdb5e77c111af6e9a9e2f2 Mon Sep 17 00:00:00 2001 From: Kai Huang Date: Fri, 6 Sep 2024 00:08:37 +1200 Subject: [PATCH] KVM: VMX: Also clear SGX EDECCSSA in KVM CPU caps when SGX is disabled When SGX EDECCSSA support was added to KVM in commit 16a7fe3728a8 ("KVM/VMX: Allow exposing EDECCSSA user leaf function to KVM guest"), it forgot to clear the X86_FEATURE_SGX_EDECCSSA bit in KVM CPU caps when KVM SGX is disabled. Fix it.
