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 | |
20 | kernel. | |
21 | If in doubt, say "N" | |

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". | |

70 | This option enables stack unwinding support in the kernel | |

73 | the performance is not affected. Currently, this feature | |

83 | help | |
84 | When a user program crashes due to an exception, the kernel can | |
85 | print a brief message explaining what the problem was. This is | |
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 | |
94 | 4 - invalid data aborts | |
95 | 8 - SIGSEGV faults | |

1826 | This option influences the normal decompressor output for | |
1827 | multiplatform kernels. Normally, multiplatform kernels disable | |
1828 | decompressor output because it is not possible to know where to | |
1829 | send the decompressor output. | |

1831 | When this option is set, the selected DEBUG_LL output method | |
1832 | will be re-used for normal decompressor output on multiplatform | |
1833 | kernels. | |
