++ * ipmi_panic.c
++ *
++ * 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.
