- Normally kallsyms only contains the symbols of functions, for nicer

- depends on KALLSYMS
- help
- If kallsyms is not working correctly, the build will fail with
- inconsistent kallsyms data. If that occurs, log a bug report and
- turn on KALLSYMS_EXTRA_PASS which should result in a stable build.
- Always say N here unless you find a bug in kallsyms, which must be
- reported. KALLSYMS_EXTRA_PASS is only a temporary workaround while
- you wait for kallsyms to be fixed.

+ 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).
+
+ Say N unless you really need all symbols.
