+Subject: [PATCH] or1k: Fix incorrect value in PLT GOT entries, causing
+ infinite loop
+
+The PLT GOT entry should point to the first PLT entry which contains the
+runtime linker function.  It was pointing back to the symbol PLT entry
+causing an infinite loop.
+
+I found this when testing the OpenRISC glibc port which uses the runtime
+dynamic linker.  It seems other libc's we use so far have not been
+making use of the initial PLT GOT entries.
+
+bfd/ChangeLog:
+
+       * elf32-or1k.c (or1k_elf_finish_dynamic_symbol): Use correct value for
+       PLT GOT entries.
+
+(cherry picked from commit 09f7b0de537d465fc8ed9f9433e348c1bc78aab2)
