Well,

some test:

scenario:

kernel: linux-3.16
ipipe-patch: ipipe-core-3.16-x86-1.patch (it's the same in the adeos repos 
that xenomai repo, I checked it ;-)
xenomai-3.git, checked today branch "next".
chroot with jessie/sid environtment. updated today.

decompress kernel and execute in the linux dir:

../xenomai-3.git/scripts/prepare-kernel.sh --linux=. --
ipipe=../xenomai-3.git/kernel/cobalt/arch/x86/patches/ipipe-core-3.16-
x86-1.patch --arch=x86


- copy an old config and do:
make oldconfig (ok)

- CONCURRENCY_LEVEL=8 CLEAN_SOURCE=no fakeroot make-kpkg --verbose --initrd --
append-to-version -xenomai-3.0.0 --revision 1.0 kernel_image kernel_headers

fails with this message:

the file init/Kconfig has in that line

if XENOMAI
source "arch/$ARCH/xenomai/Kconfig"
endif

if I put here x86 (instead of $ARCH that was x86_64), it seems it compile and 
build the packages.

Please could you put the contents here that match with the contents of the 
directory: linux-x.y.z/arch?

Also, I would like to say, that a folder with the name x86_64 was created by 
make-kpkg.


Best regadrs,

Leopold
