Were you able to get the family/model/stepping info for lib/Support/Host.cpp?

A search of the linux kernel definitions http://cinnabar.sosdg.org/~qiyong/qxr/linux/source/arch/x86/include/asm/intel-family.h#L62 suggest that steppings 0x5c, 0x7a, and 0x5f are all goldmonts.

Does GLM have faster PMULLD than silvermont or should we carry over FeatureSlowPMULLD to here?
