The following patch merges the m68k and m68knommu arch directories.
This patch has been trimmed for review purposes - the automated file
moving and mergeing carried out by the script contained in this email
has been removed. Only the manually required changes after running the
script are shown as the patch. (So to end up with the final required
change you need to run this script then apply the patch).
This change is available as the only commit on the m68knommu git tree,

It is also on the for-next branch in that tree, so will get some testing
in the next tree for the next few days.
defconfig is now a nommu-config, and it fails?
BTW, haven't tried it myself yet. I'm busy bisecting an issue with
initrds, which
got introduced between 2.6.37 and 2.6.38.
Init fails with init: cannot open inittab, followed by
Kernel panic - not syncing: Attempted to kill init!.
As I can't get ramdisks to work on ARAnyM, I need to use real hardware,
which
suffers a lot from long reboot/copy kernel/test cycles...
As one data point (though not sure how useful this is to you... :-)
I can compile for an Atari target with the merge tree and load it
and run it on ARAnyM - using a ramdisk for root fs. Seems to work
ok.
Strange. On ARAnyM I get:
Trying to unpack rootfs image as initramfs...
rootfs image is not initramfs (junk in compressed archive); looks
like an initrd
Freeing initrd memory: 350k freed
but later it fails with:
RAMDISK: Couldn't find valid RAM disk image starting at 0.
It works (i.e. mounts) on the Amiga, but later it fails with the
inittab error.
Will bisect more tonight...

Yep, that looks wrong. I'll move the define for KBUILD_DEFCONFIG
into arch/m68k/Makefile (and remove the existing defines in Makefile_mm
and Makefile_no). That will make the DEFCONFIG as it was before,
multi_defconfig.

This is due to compiling for the non-mmu targets and not using
a m68k-uclinux- toolchain. Unfortunately the compiler must define

have had this problem ever since the merge of the header files.
(The exported headers need some switch to use to base some
conditionals on, and kernel config options cannot be used in
exported headers).
For kernels, we can explicitly define this in arch/m68k/Makefile if !MMU, right?
But with a fixed defconfig, you won't see this anymore :-)
I'll fix up the git commit on m68knommu git tree.
Good, thx!

That is updated... Do you want to let this bake for another couple
of days before I ask Linus to pull it?
