Minimul Config file for Dev Environment

Hi Folks, I usually compile the linux kernel by copying current system .config file. But the problem it compile bunch things that I don't which is required. My aim is setup filesystem environmrnt setup on my laptop. Could somebody point the minimal .config file that will save from me reading all the options and compile the kernel quickly and test it. PS: I google it out, but most .config files are very old. I am hoping somebody helping me for current mainline kernel. --- Jitendra
