This patch fixes a bug within the cmpxchg GRB version. A problem was notices while running some tests to stress the priority inheritance, for example pi_stress (http://rt.wiki.kernel.org/index.php/PI_Mutex_Test). Also, without this patch, after applying the latest work to consolidate atomic_cmpxchg() definitions (commit: 8c0b8139c87cfe8b95c6e763b4ca3190aa9b1ad0) the Kernel doesn't boot at all.
