The idea of the first patch series for system call table generation support
is to replace uapi and syscall table as it is. That's why u can find places
where sys_ni_syscalls present. I have a plan for cleanup in the uapi header
and syscall table files. By that time all sys_ni_syscall removed from the
table (Hopefully).

I can post the cleanup patch asap.

In that case I don't this above change is required.
