Hi Linus,
Can you please pull the m68knommu git tree, for-next branch:
git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu.git for-next
The biggest change is the addition of MMU support for some of the ColdFire
CPU types. The older ColdFire CPUs had no MMU hardware, but some of the
newer v4 variants do. There is also quite a few clean up, dead code removal
and merge patches to gradually get the classic m68k and the m68knommu code
better integrated.
Regards
Greg
