I'm trying to port some applications from an old kernel 2.4.x project to an
up-to-date kernel 2.6.x build - all running on Coldfire with no MMU.
One of these applications accesses some coldfire IO registers directly from
userspace and it doesn't seem to be working after the port.
Is it still the case that on a m68knommu system it is possible to simply
read or write anywhere from userspace? or has some rudimentary protection
been implemented?
