These commits might be relevant:

 bdc802d: x86, cpu: Support the features flags in new CPUID leaf 7
 83a7a2a: x86, alternatives: Use 16-bit numbers for cpufeature index
 24da9c2: x86, cpu: Add CPU flags for F16C and RDRND

So you could try reverting them. If that doesnt work out please try to bisect 
it.

Thanks,

	Ingo
