+	help
+	  It is not uncommon that a document gets renamed.
+	  This option makes the Kernel to check for missing dependencies,
+	  warning when something is missing. Works only if the Kernel
+	  is built from a git tree.

+config WARN_ABI_ERRORS
+	bool "Warn if there are errors at ABI files"
+	help
+	  The files under Documentation/ABI should follow what's
+	  described at Documentation/ABI/README. Yet, as they're manually
+	  written, it would be possible that some of those files would
+	  have errors that would break them for being parsed by
+	  tools/docs/get_abi.py. Add a check to verify them.
