If you don't know your way around menuconfig, hit / to search (à la vim and friends), and type in enough of the config option to narrow it down, e.g. "strict_devmem" or just "devmem". You can then hit one of the numbers in parentheses to jump straight to the relevant menu. It's an absolute lifesaver when you need to check on a whole bunch of random options (e.g. making whatever development defconfig you've got play nicely with a systemd filesystem).

In this specific case, it should be available under "kernel hacking" as "filter access to /dev/mem".
