 * SMBIOS Processor description.  See DSP0134 Section 7.5 for more details.

 * If the handle refers to something of size 0, that type of cache is absent.
 *
 * NOTE: Although SMBIOS exports a 64-bit CPUID result, this value should not
 * be used for any purpose other than BIOS debugging.  illumos itself computes
 * its own CPUID value and applies knowledge of additional errata and processor
 * specific CPUID variations, so this value should not be used for anything.
