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".
