I am struggling to build small size with minimum time for kernel 

compilation with vanilla kernels of  kernel.org. 

As mentioned in the makehelp, I have used defconfig but unable to get 

desirable results. I have followed linuxscratch with which make 

defconfig is taking about 20 to 30 minutes of time only for 

compilation and result of that compilation the kernel  is also unable to 

boot.  Please guide which configurations should I use to get my 

kernel build fast and of minimum size.

This is my .config file:  http://fpaste.org/229718/

Seeking for guidance,

Thanks !!
