This doesn't add up. AFAICT, you're disabling MCE reporting for crash dumps and the original patch's intention was to control whether kexec should run after a machine check. And I agree with Greg that this shouldn't be configurable but instead on by default - if you get a critical error and you cannot guarantee a stable system anymore, kexec shouldn't start at all. That simple.
