          Normally kallsyms only contains the symbols of functions for nicer
          OOPS messages and backtraces (i.e., symbols from the text and inittext
-         sections). This is sufficient for most cases. And only in very rare
-         cases (e.g., when a debugger is used) all symbols are required (e.g.,
-         names of variables from the data sections, etc).

          This option makes sure that all symbols are loaded into the kernel
          image (i.e., symbols from all sections) in cost of increased kernel
          size (depending on the kernel configuration, it may be 300KiB or
          something like this).
