For embedded users, do they use CONFIG_SYSCTL at all? If not, then we
can just allow /dev/mem access when CONFIG_SYSCTL is turned on. That
should make embedded users happy.

But: I don't want to get that patch in. I just want to have the sysctl,
if just that patch doesn't make it, well, ok for me. I just think
CONFIG_STRICT_DEVMEM is superfluous when the runtime configuration
option is present.
