From 1512cdc3572dac34a1809764f9a646cde7e82407 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Sun, 1 Apr 2012 16:38:41 -0400 Subject: [PATCH] blackfin: fix cmpxchg build fails from system.h fallout Commit 3bed8d67469c ("Disintegrate asm/system.h for Blackfin [ver #2]") introduced arch/blackfin/include/asm/cmpxchg.h but has it also including the asm-generic one which causes this: CC arch/blackfin/kernel/asm-offsets.s In file included from arch/blackfin/include/asm/cmpxchg.h:125:0, from arch/blackfin/include/asm/atomic.h:10, from include/linux/atomic.h:4, from include/linux/spinlock.h:384, from include/linux/seqlock.h:29, from include/linux/time.h:8, from include/linux/timex.h:56, from include/linux/sched.h:57, from arch/blackfin/kernel/asm-offsets.c:10: include/asm-generic/cmpxchg.h:24:15: error: redefinition of '__xchg' arch/blackfin/include/asm/cmpxchg.h:82:29: note: previous definition of '__xchg' was here make[2]: *** [arch/blackfin/kernel/asm-offsets.s] Error 1 It really only needs two simple defines from asm-generic, so just use those instead.
