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

21 ---help---
22 If this option is disabled, you allow userspace (root) access to all
23 of memory, including kernel and userspace memory. Accidental
24 access to this is obviously disastrous, but specific access can
25 be used by people debugging the kernel.
26
27 If this option is switched on, the /dev/mem file only allows
28 userspace access to memory mapped peripherals.

64 help
65 When a user program crashes due to an exception, the kernel can
66 print a brief message explaining what the problem was. This is
67 sometimes helpful for debugging but serves no purpose on a
68 production system. Most people should say N here.
69
70 In addition, you need to pass user_debug=N on the kernel command
71 line to enable this feature. N consists of the sum of:
72
73 1 - undefined instruction events
74 2 - system calls
75 4 - invalid data aborts
76 8 - SIGSEGV faults
77 16 - SIGBUS faults

1611 This option influences the normal decompressor output for
1612 multiplatform kernels. Normally, multiplatform kernels disable
1613 decompressor output because it is not possible to know where to
1614 send the decompressor output.
1615
1616 When this option is set, the selected DEBUG_LL output method
1617 will be re-used for normal decompressor output on multiplatform
1618 kernels.

1654 This option helps catch unintended modifications to loadable
1655 kernel module's text and read-only data. It also prevents execution
1656 of module data. Such protection may interfere with run-time code
1657 patching and dynamic kernel tracing - and they might also protect
1658 against certain classes of kernel exploits.
1659 If in doubt, say "N".
