2012-02-07	m68k: Add shared bit to Coldfire kernel page entries	Alexander Stein
	We had problems accessing our NOR flash trough mtd. The system always got stuck at attaching UBI using ubiattach if booted from NFS or after mounting squashfs as rootfs directly from NOR flash. After some testing of the new changes introduced from v3.2-rc1 to v3.2-rc7 we had to apply the following patch to get mtd working again. [gerg: The problem was ultimately caused by allocated kernel pages not having the shared (SG) bit set. Without the SG bit set the MMU will look for page matches incorporating the ASID as well. Things like module regions allocated using vmalloc would fault when other processes run. ] Signed-off-by: Alexander Stein <alexander.stein@systec-electronic.com> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2011-12-30	m68k: page table support definitions and code for ColdFire MMU	Greg Ungerer
	The ColdFire V4e MMU is nothing like any of the other m68k MMU's. So we need to create a set of definitions and support routines for the kernels paging functions. This is largely taken from Freescales BSP code for this (though it was a 2.6.25 kernel). I have cleaned it up alot from the original.
