On some architectures, there seems to be no difference between the SMP and UP operation (same memory barriers, same LOCking), local.h simply includes asm-generic/local.h, which removes duplicated code. These patches applies on 2.6.20-rc1-git7. It depends on the patch "atomic.h : standardising atomic primitives" Signed-off-by : Mathieu Desnoyers OpenPGP public key: http://krystal.dyndns.org:8080/key/compudj.gpg Key fingerprint: 8CD5 52C3 8E3C 4140 715F BA06 3F25 A8FE 3BAE 9A68 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
