Do you actually have a source for that statement, or is it just a continuation of what looks like confusion in the Linux x86-64 header files? (Also, x86 doesn't have an incoherent instruction cache - some older x86 cores have an incoherent instruction decode _buffer_, but that's a slightly different issue with basically no effect on any sane program).
