函数名称：The Monarch's reign

函数原型：static void mce_reign(void)

返回类型：void

参数：无

898  struct mce * m = NULL
899  global_worst等于0
900  char * msg = NULL
901  char * nmsg = NULL
908  遍历可用CPU(cpu)
909  severity等于mce_severity( & per_cpu(mces_seen, cpu), tolerant, & nmsg, true)
912  如果severity大于global_worst则
913  msg等于nmsg
914  global_worst等于severity
915  m等于per_cpu(mces_seen, cpu)
924  如果m且global_worst大于等于MCE_PANIC_SEVERITY且tolerant小于3则mce_panic("Fatal machine check", m, msg)
937  如果global_worst小于等于MCE_KEEP_SEVERITY且tolerant小于3则mce_panic("Fatal machine check from unknown source", NULL, NULL)
944  遍历可用CPU(cpu)
945  memset( & per_cpu(mces_seen, cpu), 0, sizeof(structmce))
