Hi Mulyadi,
Finally after making some study on the dprintk source, i found that it can be enable by setting the config CONFIG_CPU_FREQ_DEBUG
http://codemonkey.org.uk/projects/cpufreq/
But the above link say that i need to boot the kernel with cpufreq.debug=7, am not getting how to do that.
It is a sysctl variable. sysctl -w debug.cpufreq.verbose=7
for time being i have got it working by commenting the condition which checks for this variable in the kernel code.
Thanks for your help.

Sorry, what i meant is, am unable to find other logs which are being print using dprint,(ex: in fs/nfs/proc.c) i just wanted to know should i enable few flags in the kernel in order to enable those debug messages.
We follow "not doing top posting" rule here, so please make it as your habit too :)
OK, about dprint, I absolutely have no idea. IMHO, you could find out what dprint() really is e.g whether it is similar to printk or using other mean such as netlink etc.
Assuming it's using printk() or similar, find out which facility it uses...from there...combined with syslog.conf (or syslog alike such as rsyslog), you should easily parse the output. Enabling flag? maybe, but I think no need to think about the for now.
