From 0ff29701ffad9a5d5a24344d8b09f3af7b96ffda Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Tue, 7 Dec 2021 19:30:05 +0000 Subject: [PATCH] KVM: VMX: Fix stale docs for kvm-intel.emulate_invalid_guest_state Update the documentation for kvm-intel's emulate_invalid_guest_state to rectify the description of KVM's default behavior, and to document that the behavior and thus parameter only applies to L1.
