+ * elfxx-x86.c (readonly_dynrelocs): New function.
+ (maybe_set_textrel): New function. Always prints via minfo and
+ correct "readonly" to "read-only" in warning message., replacing..
+ (_bfd_x86_elf_readonly_dynrelocs): ..this.
+ (_bfd_x86_elf_size_dynamic_sections): Correct "readonly" to
+ "read-only" in warning message. Formatting.
+ (_bfd_x86_elf_adjust_dynamic_symbol): Use readonly_dynrelocs.
+ * linker.c (bfd_link_hash_traverse): Comment typo fix.
