[debian-non-standard] building a kernel to boot debian - build process strips out lots of kernel module options

Hi!

I am just trying to use OpenWrt to build a kernel for my Debian Squeeze on 
ASUS WL-500 gP installation which still uses 2.6.30 from

http://wpkg.org/files/debian-asus/2.6.30/


This is with

URL: svn://svn.openwrt.org/openwrt/trunk
Revision: 32384


First I tried the recommended, but inofficial and possibly somewhat hacky 
approach from wpkg.org to do make ARCH=mips menuconfig inside

trunk/build_dir/linux-brcm47xx/linux-3.3.8

But then OpenWrt build process overwrites lots of options I set again from 
the target config. I tried to work around it by copying my config to the 
target one, but then I get build failures like:

make[5]: Entering directory 
`/home/martin/Computer/Gayatri/OpenWRT/trunk/build_dir/linux-
brcm47xx/linux-3.3.8'
  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  CC      arch/mips/bcm47xx/nvram.o
arch/mips/bcm47xx/nvram.c:166:12: error: 'early_nvram_init_nflash' defined 
but not used [-Werror=unused-function]
cc1: all warnings being treated as errors

make[7]: *** [arch/mips/bcm47xx/nvram.o] Error 1
make[6]: *** [arch/mips/bcm47xx] Error 2
make[5]: *** [arch/mips] Error 2
make[5]: Leaving directory 
`/home/martin/Computer/Gayatri/OpenWRT/trunk/build_dir/linux-
brcm47xx/linux-3.3.8'

even after having replaced all occurences of -Werror in any makefile by "".


Thus I went for the official make kernel_menuconfig approach. The kernel is 
now build.

But OpenWrt build process still doesn´t take all modules for the effective 
kernel configuration in trunk/build_dir/linux-brcm47xx/linux-3.3.8/.config. 
I have configured:

But I still get:

I can certainly do without XFS module, maybe it can´t work on mips anyway, 
but I do like to have the netfilter modules. (Maybe minus ebtables, cause I 
think I do not really need those.)


How can I have OpenWrt to build the kernel with exactly my configuration 
and not strip out half of the modules?

I just need a kernel inside a flash able image with my configuration and:

martin at merkaba:~/Computer/Gayatri/OpenWRT/trunk/build_dir/linux-
brcm47xx/linux-3.3.8> grep root= .config
CONFIG_CMDLINE="root=/dev/sda1 rootdelay=15 console=ttyS0,115200"


I appreciate any help. I spend lots of time and I am also willing to 
provide a HOWTO should I get through.



PS: For a proper  make ARCH=mips modules_install I added the following:

(sorry line-wrapped. I can repost this patch without wrapping in another 
mail, but when I switch KMail to no word wrapping for this long mail I 
would have to format all my free-form text by hand. I can´t set line 
wrapping on ranges in KMail.)

PPS: I am aware of DebWrt, but it doesn´t even get past the first simple 
build steps when I follow its build howto.


PPPS: I have seen ExtRoot, but I didn´t yet understand whether thats 
suitable for my usecase and how to use it.
