Sysctl support found in init/Kconfig

Help text

The sysctl interface provides a means of dynamically changing certain kernel parameters and variables on the fly without requiring a recompile of the kernel or reboot of the system. The primary interface consists of a system call, but if you say Y to "/proc file system support", a tree of modifiable sysctl entries will be generated beneath the /proc/sys directory. They are explained in the files in Documentation/sysctl/. Note that enabling this option will enlarge the kernel by at least 8 KB.

As it is generally a good thing, you should say Y here unless building a kernel for install/rescue disks or your system is very limited in memory.
