+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.
+
+# RMK wants arm kernels compiled with frame pointers or stack unwinding.
+# If you know what you are doing and are willing to live without stack
+# traces, you can get a slightly smaller kernel by setting this option to
+# n, but then RMK will have to kill you ;).
+config FRAME_POINTER

+ help
+ If you say N here, the resulting kernel will be slightly smaller and

+ when a problem occurs with the kernel, the information that is
+ reported is severely limited.
+
+config ARM_UNWIND
+ bool "Enable stack unwinding support (EXPERIMENTAL)"
+ depends on AEABI
+ default y
+ help
+ This option enables stack unwinding support in the kernel
+ using the information automatically generated by the
+ compiler. The resulting kernel image is slightly bigger but
+ the performance is not affected. Currently, this feature
+ only works with EABI compilers. If unsure say Y.

+
+config DEBUG_USER
+ bool "Verbose user fault messages"
+ help
+ When a user program crashes due to an exception, the kernel can
+ print a brief message explaining what the problem was. This is
+ sometimes helpful for debugging but serves no purpose on a
+ production system. Most people should say N here.
+
+ In addition, you need to pass user_debug=N on the kernel command
+ line to enable this feature. N consists of the sum of:
+
+ 1 - undefined instruction events
+ 2 - system calls
+ 4 - invalid data aborts
+ 8 - SIGSEGV faults
+ 16 - SIGBUS faults
+
+config DEBUG_RODATA
+ bool "Write protect kernel text section"
+ default n
+ depends on DEBUG_KERNEL && MMU
+ ---help---
+ Mark the kernel text section as write-protected in the pagetables,
+ in order to catch accidental (and incorrect) writes to such const
+ data. This will cause the size of the kernel, plus up to 4MB, to
+ be mapped as pages instead of sections, which will increase TLB
+ pressure.
+ If in doubt, say "N".
+
+config DEBUG_RODATA_TEST
+ bool "Testcase for the DEBUG_RODATA feature"
+ depends on DEBUG_RODATA

+ executes before the console is initialized.
+
+ Note that selecting this option will limit the kernel to a single
+ UART definition, as specified below. Attempting to boot the kernel
+ image on a different platform *will not work*, so this option should
+ not be enabled for kernels that are intended to be portable.
