246  These can be used to print at the various log levels.* All of these will print unconditionally, although note that pr_debug()* and other debug macros are compiled out unless either DEBUG is defined* or CONFIG_DYNAMIC_DEBUG is set.("NMI: IOCK error (debug interrupt?) for reason %02x on CPU %d.\n", reason, smp_processor_id())
