+config CC_STACKPROTECTOR
+	bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
+	depends on SUPERH32 && EXPERIMENTAL
+	help
+	  This option turns on the -fstack-protector GCC feature. This
+	  feature puts, at the beginning of functions, a canary value on
+	  the stack just before the return address, and validates
+	  the value just before actually returning.  Stack based buffer
+	  overflows (that need to overwrite this return address) now also
+	  overwrite the canary, which gets detected and the attack is then
+	  neutralized via a kernel panic.
+
+	  This feature requires gcc version 4.2 or above.
