 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.
 16           If in doubt, say "N"

 20 # traces, you can get a slightly smaller kernel by setting this option to

 27           If you say N here, the resulting kernel will be slightly smaller and
 28           faster. However, if neither FRAME_POINTER nor ARM_UNWIND are enabled,
 29           when a problem occurs with the kernel, the information that is

 37           This option enables stack unwinding support in the kernel
 38           using the information automatically generated by the
 39           compiler. The resulting kernel image is slightly bigger but
 40           the performance is not affected. Currently, this feature
 41           only works with EABI compilers. If unsure say Y.

 51           When a user program crashes due to an exception, the kernel can
 52           print a brief message explaining what the problem was. This is
 53           sometimes helpful for debugging but serves no purpose on a
 54           production system. Most people should say N here.
 55 
 56           In addition, you need to pass user_debug=N on the kernel command
 57           line to enable this feature.  N consists of the sum of:
 58 
 59               1 - undefined instruction events
 60               2 - system calls
 61               4 - invalid data aborts
 62               8 - SIGSEGV faults
 63              16 - SIGBUS faults

1671           This option influences the normal decompressor output for
1672           multiplatform kernels.  Normally, multiplatform kernels disable
1673           decompressor output because it is not possible to know where to
1674           send the decompressor output.
1675 
1676           When this option is set, the selected DEBUG_LL output method

1705           Enabling this option causes the kernel to write the current PID to

1714           This option helps catch unintended modifications to loadable
1715           kernel module's text and read-only data. It also prevents execution
1716           of module data. Such protection may interfere with run-time code
1717           patching and dynamic kernel tracing - and they might also protect
1718           against certain classes of kernel exploits.
1719           If in doubt, say "N".
