+Subject: KVM: VMX: Fix stale docs for kvm-intel.emulate_invalid_guest_state
+
+From: Sean Christopherson <seanjc@google.com>
+
+commit 0ff29701ffad9a5d5a24344d8b09f3af7b96ffda upstream.
+
+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.
+
+Fixes: a27685c33acc ("KVM: VMX: Emulate invalid guest state by default")
