That document changes from version to version as to what we _think_ the actual hardware does. It is _NOT_ a specification. You cannot design hardware from that. Its incomplete and fails to specify a bunch of things. It not a mathematically sound definition of a memory model. Please stop referring to that document for what a particular barrier _should_ do. Explain what MIPS does, so we can attempt to integrate this knowledge with our knowledge of PPC/ARM/Alpha/x86/etc. and improve upon our understanding of hardware and improve the Linux memory model. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
