Message-ID: <20070410222753.GB7092@Krystal> Date: Tue, 10 Apr 2007 18:27:53 -0400 From: Mathieu Desnoyers <mathieu.desnoyers@...ymtl.ca> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-kernel@...r.kernel.org Subject: [PATCH] atomic-powerpc-remove-double-defines Remove duplicated defines in asm-powerpc/atomic.h. atomic64_inc_not_zero and atomic64_xchg are defined twice. It also removes an unnecessary cast to the atomic_cmpxchg result, which is already done by system.h cmpxchg. It applies on 2.6.21-rc6-mm1.
