From what I can see from these docs, Intel's "IA-32e" is very very close to the natural combination of P4 with AMD64. No hyperlink stuff, but otherwise the same. The local APIC and performance counters should be exactly as in P4 :-)
What about naming? IA-64 is taken, AMD64 is too specific, Intel's "IA-32e" sounds too vague, and I find x86-64 / x86_64 difficult to type. "x64" perhaps? - 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/
