Ok 2-3 hours before I did this mistake I did
make world without using config from /boot
so I failed and got errors.
Next time I did make clean

but this time my internet connection got disconnected so it hanged here


 git clone -o xen -n
git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git
linux-2.6-pvops.git.tmp

I think these files are already present is there a way to by pass this
because now if I type
make world and things begin from scratch again then it again will
start downloading things from
internet which keeps disconnecting.
Is there a way to get rid of this situation.
