* While adding a new CPUID for a new microarchitecture, add a new
* group to keep logically sorted out in chronological order. Within
* that group keep the CPUID for the variants sorted by model number.
+ *
+ * The defined symbol names have the following form:
+ * INTEL_FAM6{OPTFAMILY}_{MICROARCH}{OPTDIFF}
+ * where:
+ * OPTFAMILY Describes the family of CPUs that this belongs to. Default
+ * is assumed to be "_CORE" (and should be omitted). Other values
+ * currently in use are _ATOM and _XEON_PHI
+ * MICROARCH Is the code name for the micro-architecture for this core.
+ * N.B. Not the platform name.
+ * OPTDIFF If needed, a short string to differentiate by market segment.
+ * Exact strings here will vary over time. _DESKTOP, _MOBILE, and
+ * _X (short for Xeon server) should be used when they are
+ * appropriate.
+ *
+ * The #define line may optionally include a comment including platform names.
