9 ---help---
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.
28
29 If in doubt, say Y.

50 This option enables stack unwinding support in the kernel
51 using the information automatically generated by the
52 compiler. The resulting kernel image is slightly bigger but
53 the performance is not affected. Currently, this feature
54 only works with EABI compilers. If unsure say Y.

62 bool "Verbose user fault messages"
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

484 This option should be used with the old bootloaders
485 that left the internal registers mapped at
486 0xd0000000. As of today, this is the case on
487 platforms such as the Globalscale Mirabox or the
488 Plathome OpenBlocks AX3, when using the original
489 bootloader.

491 If the wrong DEBUG_MVEBU_UART* option is selected,
492 when u-boot hands over to the kernel, the system
493 silently crashes, with no serial output at all.

1551 This option influences the normal decompressor output for
1552 multiplatform kernels. Normally, multiplatform kernels disable
1553 decompressor output because it is not possible to know where to
1554 send the decompressor output.
1555
1556 When this option is set, the selected DEBUG_LL output method
1557 will be re-used for normal decompressor output on multiplatform
1558 kernels.
