From 70f4cc29350222ff6baf70265f6482fc01565d48 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 10 May 2009 14:26:52 +0000 Subject: [PATCH] microblaze: kill incorrect __bad_xchg definition The whole point of the __bad_xchg declaration in system.h is to give a linker error when a variable of invalid size is passed to __xchg. The out of line definition in traps.c defeats this purpose and does not any value, so remove it here.
