[PATCH 00/35 v2] m68k: ColdFire MMU support

Hi All,

This is version 2 of a patch set that adds support for running the V4e
ColdFire cores with their MMU enabled. A bit of cleanup and some fixes over
the first version. In particular the following changes:

. rebased onto 3.2-rc3
. fixed FPU support
. fixed running with shared libraries
. fixed running at non-0 based RAM (thanks to Alexander Stein)
. many random small cleanups
. spelling and comment fixes

This patch set is based on 3.2-rc3 with all the recent patches I have sent
here applied first. It is available as a git tree for easier testing, just
pull this tree, with the cfmmu branch:

git://git.kernel.org/pub/scm/linux/kernel/git/gerg/m68knommu.git cfmmu

Some of the code in this set is taken from Freescales 2.6.25 kernel support
of MMU ColdFire.

Specifically I am testing this on a ColdFire 5475 (on a FireBee board).
I have test compiled and run this patch set on ARAnyM as well, I didn't have
any problems there. Also test compiled and run on MMU-less ColdFire.

Geert, any patches that changed in any significant way I dropped your
"Acked-by".

Regards
Greg
