  16	  Say Y here if you want to show the kernel pagetable layout in a
  17	  debugfs file. This information is only useful for kernel developers
  18	  who are working in architecture specific areas of the kernel.
  19	  It is probably not a good idea to enable this feature in a production

  27	---help---
  28		Generate a warning if any W+X mappings are found at boot.
  29
  30		This is useful for discovering cases where the kernel is leaving
  31		W+X mappings after applying NX, as such mappings are a security risk.
  32
  33		Look for a message in dmesg output like this:
  34
  35			arm/mm: Checked W+X mappings: passed, no W+X pages found.
  36
  37		or like this, if the check failed:
  38
  39			arm/mm: Checked W+X mappings: FAILED, <N> W+X pages found.
  40
  41		Note that even if the check fails, your kernel is possibly
  42		still fine, as W+X mappings are not a security hole in
  43		themselves, what they do is that they make the exploitation
  44		of other unfixed kernel bugs easier.
  45
  46		There is no runtime or memory usage effect of this option
  47		once the kernel has booted up - it's a one time check.
  48
  49		If in doubt, say "Y".

  86	  sometimes helpful for debugging but serves no purpose on a
  87	  production system. Most people should say N here.
  88
  89	  In addition, you need to pass user_debug=N on the kernel command
  90	  line to enable this feature.  N consists of the sum of:
  91
  92	      1 - undefined instruction events
  93	      2 - system calls
