+# List references to vmlinux init sections from non-init sections.
+
+# Unfortunately I had to exclude references from read only data to .init
+# sections, almost all of these are false positives, they are created by
+# gcc.  The downside of excluding rodata is that there really are some
+# user references from rodata to init code, e.g. drivers/video/vgacon.c
+#
+# const struct consw vga_con = {
+#        con_startup:            vgacon_startup,
+#
+# where vgacon_startup is __init.  If you want to wade through the false
+# positives, take out the check for rodata.
