system call

[Nitin Varyani]

I have a 64 bit machine

I am changing linux 3.5.4 source tree.

I modified syscall_64.tbl
I had put your code in linux_3.5.4/arch/x86/pks_first/pks_first_call.c

Then, I created pks_first/Makefile

Modified the arch/x86/Kbuild

Modified include/linux/syscalls.h


I ran "make menuconfig" and then simply exit.

Then I ran

"make"

I saw that pks_first_call.o was created

I then ran

"make modules_install"
"make install"

After then I restarted my system and booted linux 3.5.4. But it was stuck
half way.
