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,
for-linux branch:

The following changes since commit a952baa034ae7c2e4a66932005cbc7ebbccfe28d:
  Linus Torvalds (1):
        Merge branch 'for-linus' of git://git.kernel.org/.../dtor/input

Greg Ungerer (1):
      m68k: merge m68k and m68knommu arch directories


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.

I have done some testing on both MMU and non-MMU targets, and they
worked fine. I tried a few ColdFire non-MMU builds, and I built and
ran the Atari target in the AranyM emulator. Other than some option
re-ordering the configs produced are the same.

If everyone is happy I would like to ask Linus to pull this before the
end of the current merge window.

Regards
Greg
