CONFIG_KALLSYMS suffices.

 	  This adds debug symbols to the kernel and modules (gcc -g), and
 	  is needed if you intend to use kernel crashdump or binary object
 	  tools like crash, kgdb, LKCD, gdb, etc on the kernel.
-	  Say Y here only if you plan to debug the kernel.

+	  If you only want to have resolved symbols in kernel traces and
+	  are not going to need support for those tools above, you don't need
+	  to enable this as it is a huge bloat and build slowdown;
+	  enable CONFIG_KALLSYMS instead.
 
 	  If unsure, say N.
