Well, it's a very little thing in the header file /usr/include/asm-i486/cpufeature.h (...) #define X86_FEATURE_MCE (0*32+ 7) /* Machine Check Architecture */ (...) #define X86_FEATURE_MCA (0*32+14) /* Machine Check Architecture */ (...) two flags for the same behavior? maybe the first one is Machine Check *Exception*
Yup, care to send a patch to LKML ?
