13 | Say Y here if you want to show the kernel pagetable layout in a |
14 | debugfs file. This information is only useful for kernel developers | |
15 | who are working in architecture specific areas of the kernel. | |
16 | It is probably not a good idea to enable this feature in a production | |
17 | kernel. | |
18 | If in doubt, say "N" | |

25 | Generate a warning if any W+X mappings are found at boot. |
26 | ||
27 | This is useful for discovering cases where the kernel is leaving | |
28 | W+X mappings after applying NX, as such mappings are a security risk. | |
29 | ||
30 | Look for a message in dmesg output like this: | |
31 | ||
32 | arm/mm: Checked W+X mappings: passed, no W+X pages found. | |
33 | ||
34 | or like this, if the check failed: | |
35 | ||
36 | arm/mm: Checked W+X mappings: FAILED, <N> W+X pages found. | |
37 | ||
38 | Note that even if the check fails, your kernel is possibly | |
39 | still fine, as W+X mappings are not a security hole in | |
40 | themselves, what they do is that they make the exploitation | |
41 | of other unfixed kernel bugs easier. | |
42 | ||
43 | There is no runtime or memory usage effect of this option | |
44 | once the kernel has booted up - it's a one time check. | |
45 | ||
46 | If in doubt, say "Y". | |

99 | When a user program crashes due to an exception, the kernel can | |

101 | sometimes helpful for debugging but serves no purpose on a | |
102 | production system. Most people should say N here. | |

104 | In addition, you need to pass user_debug=N on the kernel command | |
105 | line to enable this feature. N consists of the sum of: | |

1816 | This option influences the normal decompressor output for | |
1817 | multiplatform kernels. Normally, multiplatform kernels disable | |
1818 | decompressor output because it is not possible to know where to | |
1819 | send the decompressor output. | |

1821 | When this option is set, the selected DEBUG_LL output method | |
1822 | will be re-used for normal decompressor output on multiplatform | |
1823 | kernels. | |
