Subject: [PATCH 3/4] xen: link platform-pci-unplug.o only if CONFIG_XEN_PVHVM
Date:   Tue, 17 Jul 2018 14:01:12 +0200
Message-Id: <20180717120113.12756-4-jgross@suse.com>
In-Reply-To: <20180717120113.12756-1-jgross@suse.com>
References: <20180717120113.12756-1-jgross@suse.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Instead of using one large #ifdef CONFIG_XEN_PVHVM in
arch/x86/xen/platform-pci-unplug.c add the object file depending on
CONFIG_XEN_PVHVM being set.
