+config DEBUG_RODATA

+       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 TLB anymore.
+         If in doubt, say "N".

+config DEBUG_STRICT_USER_COPY_CHECKS
+	bool "Strict copy size checks"
+	depends on DEBUG_KERNEL && !TRACE_BRANCH_PROFILING
+	---help---
+	  Enabling this option turns a certain set of sanity checks for user
+	  copy operations into compile time failures.
+
+	  The copy_from_user() etc checks are there to help test if there
+	  are sufficient security checks on the length argument of
+	  the copy operation, by having gcc prove that the argument is
+	  within bounds.
+
+	  If unsure, or if you run an older (pre 4.4) gcc, say N.
