In building zImage, objcopy strips these symbols (and all others);
the kernel's EXPORT_SYMBOL macro is needed to export them. For
unknown reasons, they were missing from net/netsyms.c. Adding
this block remedies the issue:

+#if defined(CONFIG_INET_ESP) || defined(CONFIG_INET_ESP_MODULE) || 
defined(CONF
IG_INET6_ESP) || defined(CONFIG_INET6_ESP_MODULE)
+EXPORT_SYMBOL_GPL(skb_cow_data);
+EXPORT_SYMBOL_GPL(pskb_put);
+EXPORT_SYMBOL_GPL(skb_to_sgvec);
+#endif
