+source "lib/Kconfig.debug"
+
+config FRAME_POINTER
+	bool
+	default y
+
+config DEBUG_STACK_USAGE
+	bool "Enable stack utilization instrumentation"
+	depends on DEBUG_KERNEL
+	help
+	  Enables the display of the minimum amount of free stack which each
+	  task has ever had available in the sysrq-T output.
+
+config STRICT_DEVMEM
+	bool "Filter access to /dev/mem"
+	depends on MMU
+	help
+	  If this option is disabled, you allow userspace (root) access to all
+	  of memory, including kernel and userspace memory. Accidental
+	  access to this is obviously disastrous, but specific access can
+	  be used by people debugging the kernel.
+
+	  If this option is switched on, the /dev/mem file only allows
+	  userspace access to memory mapped peripherals.
+
+	  If in doubt, say Y.
+
+config EARLY_PRINTK
+	bool "Early printk support"
+	default y
+	help
+	  Say Y here if you want to have an early console using the
+	  earlyprintk=<name>[,<addr>][,<options>] kernel parameter. It
+	  is assumed that the early console device has been initialised
+	  by the boot loader prior to starting the Linux kernel.
+
+config PID_IN_CONTEXTIDR
+	bool "Write the current PID to the CONTEXTIDR register"
+	help
+	  Enabling this option causes the kernel to write the current PID to
+	  the CONTEXTIDR register, at the expense of some additional
+	  instructions during context switch. Say Y here only if you are
+	  planning to use hardware trace tools with this kernel.
+
+config DEBUG_SET_MODULE_RONX
+        bool "Set loadable kernel module data as NX and text as RO"
+        depends on MODULES
+        help
+          This option helps catch unintended modifications to loadable
+          kernel module's text and read-only data. It also prevents execution
+          of module data. Such protection may interfere with run-time code
+          patching and dynamic kernel tracing - and they might also protect
+          against certain classes of kernel exploits.
+          If in doubt, say "N".
