Hrm, does the file

arch/powerpc/include/asm/immediate.h exist in your tree ?

Here, with the setup done following the commands I gave you (minus the
mkdir patch), I get :


compudj@ok:~$ head testpaulmck/linux-2.6.29-rc3/arch/powerpc/include/asm/immediate.h
#ifndef _ASM_POWERPC_IMMEDIATE_H
#define _ASM_POWERPC_IMMEDIATE_H

/*
* Immediate values. PowerPC architecture optimizations.
*
* (C) Copyright 2006 Mathieu Desnoyers <mathieu.desnoyers@xxxxxxxxxx>

* This file is released under the GPLv2.
* See the file COPYING for more details.

....

Which defines struct __imv. So hrm, normally the header should be there.
(/me still confused) :)
