NAK - this adds a pile of memory wasting complete crap to every kernel
including embedded systems. At least before you could turn it off now you
can't.
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.
