But without this small patch, CPUID_7_EDX is 17 instead of NCAPINTS(19)-1=18 in patch 0002. Of course CPUID_7_EDX is 18 correctly evetually after applying patch 0003 which add the word 12 back. KVM reports this CPUID_7_EDX is not 18 in bisect (as Sena also pointed out). I think even native kernel should have some check to report this error (similar to other checks of NCAPINTS).
