Adding new system call into linux

[dumb]

Hi guys,

I'm adding a new system call into user mode linux (fedora core 2)
and i have successfully adding a new system call into user mode linux,

However, I wonder if i can make this system call available to all linux architectures, not just
user mode linux architectures) And how i would do it, or any suggestion how i should start,
thanks alot
