It is known, that Windows 8 will get support for a new security feature called Intel SMEP. I'll omit the description what's that for because more important is Linux has had this feature since spring of the last year! And that is not all of it! Today one more technology that is to debut in next year's Intel Haswell line of processors got it's way into Linux kernel. Supervisor Mode Access Prevention.
