/**

*
|
|
* @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
