// From Todd Allen:
//
// MSR_CPUID_table* is a table that appears in Intel document 325462, "Intel 64
// and IA-32 Architectures Software Developer's Manual Combined Volumes: 1, 2A,
// 2B, 2C, 2D, 3A, 3B, 3C, 3D, and 4" (the name changes from version to version
// as more volumes are added). The table moves around from version to version,
// but in version 071US, was in "Volume 4: Model-Specific Registers", Table 2-1:
// "CPUID Signature Values of DisplayFamily_DisplayModel".
// MRG* is a table that forms the bulk of Intel Microcode Revision Guidance (or
// Microcode Update Guidance). Its purpose is not to list CPUID values, but
// it does so, and sometimes lists values that appear nowhere else.
// LX* indicates features that I have seen no documentation for, but which are
// used by the Linux kernel (which is good evidence that they're correct).
// The "hook" to find these generally is an X86_FEATURE_* flag in:
// arch/x86/include/asm/cpufeatures.h
// For (synth) and (uarch synth) decoding, it often indicates
// family/model/stepping value which are documented nowhere else. These usually
// can be found in:
// arch/x86/include/asm/intel-family.h
