+# Based on the vmlinux file create the System.map file
+# System.map is used by module-init tools and some debugging
+# tools to retrieve the actual addresses of symbols in the kernel.
+#
+# Usage
+# mksysmap vmlinux System.map [exclude]
+
+
+#####
+# Generate System.map (actual filename passed as second argument)
+# The following refers to the symbol type as per nm(1).
+
+# readprofile starts reading symbols when _stext is found, and
+# continue until it finds a symbol which is not either of 'T', 't',
+# 'W' or 'w'.
