/**
 *
 * @brief Print kernel debugging message.
 *
 * This routine prints a kernel debugging message to the system console.
 * Output is send immediately, without any mutual exclusion or buffering.
 *
 * A basic set of conversion specifier characters are supported:
 *   - signed decimal: \%d, \%i
 *   - unsigned decimal: \%u
 *   - unsigned hexadecimal: \%x (\%X is treated as \%x)
 *   - pointer: \%p
 *   - string: \%s
 *   - character: \%c
 *   - percent: \%\%
 *
 * Field width (with or without leading zeroes) is supported.
 * Length attributes h, hh, l, ll and z are supported. However, integral
 * values with %lld and %lli are only printed if they fit in a long
 * otherwise 'ERR' is printed. Full 64-bit values may be printed with %llx.
 * Flags and precision attributes are not supported.
 *
 * @param fmt Format string.
 * @param ... Optional list of format arguments.
 *
 * @return N/A
