Please don't commit this. We work just fine on AMD dual-core. The patch to disable cores on Intel Hyperthreaded CPU's does not affect AMD dual-core in one bit. The author nicely took the different vendors into account. AMD sets the CPUID.HTT simply for licensing issues - something that does not affect FreeBSD at all. If there is something needed for Intel dual-core CPU's with HyperThreading to use the real cores, but not the virtual cores - then by all means please commit it. > Please test and let me know.
