From f94d1d3a1df125461a16b2888eca46d64f113e3a Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers Date: Thu, 7 Feb 2008 00:16:18 -0800 Subject: [PATCH] Fix m32r __xchg the #endif /* CONFIG_SMP */ should cover the default condition, or it may cause bad parameter to be silently missed. To make it work correctly, we have to remove the ifdef CONFIG SMP surrounding __xchg_called_with_bad_pointer declaration. Thanks to Adrian Bunk for detecting this.
