Subject: [PATCH] x86_64 - Use non locked version for local_cmpxchg()
Date: Fri, 13 Jul 2007 21:19:13 -0400 [thread overview]
Message-ID: <20070714011913.GB31649@Krystal> (raw)
x86_64 - Use non locked version for local_cmpxchg()
local_cmpxchg() should not use any LOCK prefix. This change probably got lost in
the move to cmpxchg.h.
