Hi Satish,

I don't know much about the kernel build process, so I don't know
whether it would work or not.

But you could try running make with the -n option first to see the
commands that are going to be executed.  That way you can figure out
how many files are going to be compiled.

I hope that works for you.

Regards,

bob
