-       bool "Debug __init statements"
-       depends on DEBUG_KERNEL
-       help
-         Fill __init and __initdata at the end of boot. This helps debugging
-         illegal uses of __init and __initdata after initialization.
+config DEBUG_RODATA
+       bool "Write protect kernel read-only data structures"
+       depends on DEBUG_KERNEL
+       help
+        Mark the kernel read-only data as write-protected in the pagetables,
+        in order to catch accidental (and incorrect) writes to such const data.
+        This option may have a slight performance impact because a portion
+        of the kernel code won't be covered by a 2MB TLB anymore.
+        If in doubt, say "N".
