How to add rules in Linux kernel Makefile

Question

I want to add systemcall to Linux kernel 3.6.x. I have two files myheader.h and mycode.c.

As I have seen on some articles, I did the following:

1. Create a folder from root directory /linux/myfolder.

2. Create Makefile in myfolder with the rule:

   obj-y := mycode.o

   and I put mycode.c file in this folder.

3. I modify the main Makefile form the root directory.

   core-y := usr/ myfolder/

Where should I put myheader.h and what rules should I have to add to the makefiles ?

I tried putting it inside /linux/include but it fails to compile.

You can have header file locally(within same directory as source file), and include it with simple #include "myheader.h".
