2.6-test4: mpspec.h:6:25: mach_mpspec.h: Missing file

Hi. 
I'm trying to build a (add-on) module 
on a machine booted from a 2.6-test4 kernel,
And keep running into this error. I've 
included a sample program , and gcc command
line.

I built the kernel:

make defconfig; 

It is a 2W SMP (Compaq ML850)
couple minor modes like enet & SCSI device
make
My general question is, should I include the 

-I/work/src/<build>/include/asm-i386/mach-generic/mach_mpspec.h

in my gcc command line or is my build area incorrect
is
some way that the correct mpspec.h file can't be found
?

Thx. JD.

See linux/Documentation/modules.txt and Documentation/kbuild/makefiles.txt
for how to do this properly.  Basically put your source and Makefile
in a subdir, then use this command and it builds without that error.
(Your source had a few other warnings, but it does build this way.)

Here's the Makefile that I used, with usage info in it:

# makefile for addonmodule
# Randy Dunlap, 2003-02-21
# usage:
# cd /path/to/kernel/source && make SUBDIRS=/path/to/source/addonmodule/ modules

obj-m := addonmodule.o
