Okay, that is utter nonsense. /proc/cpuinfo has always been, and will always be, the CPU *AS THE KERNEL SEES IT*. If you want something else, use x86info(1).

What a lovely way of syncing reality with your definitions. The kernel
_does_ see that my CPU features PAT, it just refuses to use it because
it doesn't trust it enough. Vital difference. Maybe not to the kernel,
but definitely to me, the user. /proc/cpuinfo is a user interface.


No, /proc/cpuinfo is informing the user about the kernel's view of the CPU. It has always been the "cooked" view of CPUID, whether or not you like it.
