Now that the _relaxed() accessors are available throughout the kernel, everyone should be using the _relaxed() versions unless they need the properties of the non-relaxed versions. Remember that the non-relaxed versions are rather expensive on ARM due to the need to go all the way out to the L2 cache - it at least doubles the number of accesses for every read*/write*(). -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
