Yeah, here:

init/Kconfig:
...
config BASE_SMALL
	int
	default 0 if BASE_FULL
	default 1 if !BASE_FULL
...
config BASE_FULL
	default y
	bool "Enable full-sized data structures for core" if EMBEDDED
	help
	  Disabling this option reduces the size of miscellaneous core
	  kernel data structures. This saves memory on small machines,
