From 9d43f4bd4365eec06dfefc55f5b0c3f40c848a05 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Tue, 15 Mar 2011 12:26:14 +0100 Subject: [PATCH] s390: Detect invalid invocations of qemu_ram_free/remap This both detects invalid invocations of qemu_ram_free and qemu_ram_remap when mem_path is non-NULL and fixes a build error on s390 ("'area' may be used uninitialized in this function").
