      The mcelog daemon accounts memory and some other errors in various ways
      on modern x86 Linux systems. The daemon can be queried and/or execute
      triggers when configurable error thresholds are exceeded. This is used to
      implement a range of automatic predictive failure analysis algorithms,
      including bad page offlining and automatic cache error handling. All
      errors are logged to /var/log/mcelog or syslog or the journal.
