From 5ae4443010b83cce3d55ce5259870e542a7c9551 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Mon, 27 Nov 2017 09:11:51 +0100 Subject: [PATCH] x86/jailhouse: Silence ACPI warning Jailhouse support does not depend on ACPI, and does not even use it. But if it should be enabled, avoid warning about its absence in the platform.
