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

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

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

89 image on a different platform *will not work*, so this option should

1236 This option influences the normal decompressor output for
1237 multiplatform kernels. Normally, multiplatform kernels disable
1238 decompressor output because it is not possible to know where to
1239 send the decompressor output.
1240
1241 When this option is set, the selected DEBUG_LL output method
1242 will be re-used for normal decompressor output on multiplatform
1243 kernels.

1256 Say Y here if you want to have an early console using the
1257 kernel low-level debugging functions. Add earlyprintk to your
1258 kernel parameters to enable this console.

1278 Enabling this option causes the kernel to write the current PID to
1279 the PROCID field of the CONTEXTIDR register, at the expense of some
1280 additional instructions during context switch. Say Y here only if you
1281 are planning to use hardware trace tools with this kernel.

1285 depends on MODULES
1286 ---help---
1287 This option helps catch unintended modifications to loadable
1288 kernel module's text and read-only data. It also prevents execution
1289 of module data. Such protection may interfere with run-time code
1290 patching and dynamic kernel tracing - and they might also protect
1291 against certain classes of kernel exploits.
1292 If in doubt, say "N".
