Hi Greg,
You have misunderstood the question. That, too, because me being too brief.
What I tried to mean is NOT to test the syscall after the modified kernel is compiled and booted. That's easy.
To add the syscall to the kernel, one needs to drop a C code implementing the body of the call itself to some appropriate location of the kernel source tree. Isn't it so? I am doing that for the first time and want to be sure that the compilation, especially the includes work. Otherwise, the kernel compilation may throw an error midway, thereby wasting my time.

Did you try:
man 2 syscall
