Does anyone know where internal.h wen with kernel 3.7?

Hello. I was building kernel 3.7 for a UML system. I was building using the um arch and got some issues.
So I googled it and found out that Linux/arch/um/kernel/internal.h is not in my kernel 3.7 folder. It is normally included in arch/um/kernel/exec.c so I think this is the problem. Does anyone know if it was moved or changed?

Thanks.
