When the HTT flag CPUID.1.EDX[HTT] is 0, it indicates that there is
only a single logical processor in the package. When HTT is 1, it
indicates that CPUID.1.EBX[23:16] contains the number of logical
processors in the package.
When this information is not included in CPUID leaf 0x1, some cpu
topology enumeration software such as hwloc are known to crash.
