You can synchronize the cmpxchg() itself using a spinlock on such platforms, but you cannot synchronize the accesses done by other processors which do not use cmpxchg(). So using cmpxchg() would block out such platforms from being able to use the tg3 driver any longer, which really isn't an option. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
