Pls review 7142113: Add Ivy Bridge to the known Intel x86 cpu families (S)

[Vladimir Kozlov]

Wikipedia also points two models

http://en.wikipedia.org/wiki/Intel_Sandy_Bridge_%28microarchitecture%29

All Sandy Bridge processors with one, two, or four cores report the same CPUID model 0206A7h (0x2A) and are closely 
related... The later Sandy Bridge-E processors with up to six cores and no graphics are using CPUID 0206D6h (0x2D).
