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.
