+config IKCONFIG
+	bool "Kernel .config support"
+	---help---
+	  This option enables the complete Linux kernel ".config" file
+	  contents, information on compiler used to build the kernel,
+	  kernel running when this kernel was built and kernel version
+	  from Makefile to be saved in kernel. It provides documentation
+	  of which kernel options are used in a running kernel or in an
+	  on-disk kernel.  This information can be extracted from the kernel
+	  image file with the script scripts/extract-ikconfig and used as
+	  input to rebuild the current kernel or to build another kernel.
+	  It can also be extracted from a running kernel by reading
+	  /proc/ikconfig/config and /proc/ikconfig/built_with, if enabled.
+	  /proc/ikconfig/config will list the configuration that was used
+	  to build the kernel and /proc/ikconfig/built_with will list
+	  information on the compiler and host machine that was used to
+	  build the kernel.
