lib/hexdump
Based on ace_dump_mem() from Grant Likely for the Xilinx SystemACE CompactFlash interface. Add print_hex_dump() & hex_dumper() to lib/hexdump.c and linux/kernel.h. This patch adds the functions print_hex_dump() & hex_dumper(). print_hex_dump() can be used to perform a hex + ASCII dump of data to syslog, in an easily viewable format, thus providing a common text hex dump format. hex_dumper() provides a dump-to-memory function. It converts one "line" of output (16 bytes of input) at a time. Example usages: print_hex_dump(KERN_DEBUG, DUMP_PREFIX_ADDRESS, frame->data, frame->len); hex_dumper(frame->data, frame->len, linebuf, sizeof(linebuf)); Example output using %DUMP_PREFIX_OFFSET: 0009ab42: 40414243 44454647 48494a4b 4c4d4e4f-@ABCDEFG HIJKLMNO Example output using %DUMP_PREFIX_ADDRESS: ffffffff88089af0: 70717273 74757677 78797a7b 7c7d7e7f-pqrstuvw xyz{|}~.
