In linux kernel since version 3.1 (release Date: 2011-10-24)
Compiles the kernel with DWARF unwind information and can be used
to get stack backtraces.
If you say Y here the resulting kernel image will be slightly larger
but not slower, and it will give very useful debugging information.
If you don't debug the kernel, you can say N, but we may not be able
to solve problems without frame unwind information
to get stack backtraces.
