But actually that routine is never executed. I had written it but now its not used and never gets called any time then how can it make so many gpfs?

Then why is it included in your post?
Try
reducing scope. Do some debugging.

Combuster showed you one place where you have a great mistake, but you have this mistake in many other places too.
Just think about size of `word' and `eax'.
I'm feeling tired of this madness.. although i'm remembering that about 5 years ago i've done the same mistake.

Only 5 days to only find out what garbage value you attempt to put in a segment register?
Do some debugging. Get yourself the line of code.

I am replying to this post almost after few months. i got it solved and it was too silly mistake. at a place before my kernel_main() i had done cli and so i got interrupts after i had done sti. and the gpf one is bcoz in my irq instead of jmp i had done call and so may be stack was getting messed up.
i had got solution to dis a long ago. today i was simply going through this post so thought of telling that i had got the solution.
