This problem had been introduced by '575203b4747c(x86, MCE, AMD: Disable error thresholding bank 4 on some models)' and '2e6f694fde0a(x86, mce: port K7 bank 0 quirk to 64bit mce code)' This may be an insignificant patch. However, if we allow them continue to survive, then this may make someone uncomfortable.
