	bool "Export kernel pagetable layout to userspace via debugfs"
	depends on DEBUG_KERNEL
	depends on MMU
	select ARM_PTDUMP_CORE
	select DEBUG_FS
	help
	  Say Y here if you want to show the kernel pagetable layout in a
	  debugfs file. This information is only useful for kernel developers
	  who are working in architecture specific areas of the kernel.
	  It is probably not a good idea to enable this feature in a production
	  kernel.
	  If in doubt, say "N"

config DEBUG_WX
	bool "Warn on W+X mappings at boot"
	depends on MMU
	select ARM_PTDUMP_CORE
	help
		Generate a warning if any W+X mappings are found at boot.

This is useful for discovering cases where the kernel is leaving
		W+X mappings after applying NX, as such mappings are a security risk.

Look for a message in dmesg output like this:

arm/mm: Checked W+X mappings: passed, no W+X pages found.

or like this, if the check failed:

arm/mm: Checked W+X mappings: FAILED, <N> W+X pages found.

Note that even if the check fails, your kernel is possibly
		still fine, as W+X mappings are not a security hole in
		themselves, what they do is that they make the exploitation
		of other unfixed kernel bugs easier.

There is no runtime or memory usage effect of this option
		once the kernel has booted up - it's a one time check.

If in doubt, 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

# These options are only for real kernel hackers who want to get their hands dirty.

	  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.

	  This option influences the normal decompressor output for

	  decompressor output because it is not possible to know where to
