I just noticed that this breaks IPv4 addresses in IPVS debug output
(didn't check in other places). It seems that during integer to ASCII
conversion, the converted digits are output the wrong way around (not
endianness though). For example, 10.0.0.254 is output as 01.0.0.452.
Could something be wrong with ip4_addr_string() or put_dec_trunc() in
lib/vsprintf.c?
