+ * This code is needed to run a streamlined IPMI KCS command when
+ * the rest of the system may be dead (panic time).  It must wait
+ * for completion of the receive function also.
+ * There will be zero or one BMC, with KCS as a minimum and perhaps
+ * other interfaces, so doing KCS to a default BMC LUN is valid here.
+ * 
+ * Note that CONFIG_IPMI_HANDLER should be =y (rather than =m) to 
+ * ensure that this handler is loaded early enough to cover boot
+ * time panic conditions.  CONFIG_IPMI_PANIC_ACTION can only be
+ * defined if CONFIG_IPMI_HANDLER=y.
