+Subject: [PATCH] warn on all TEXTRELs
+
+textrels are bad for forcing copy-on-write (this affects everyone),
+and for security/runtime code generation, this affects security ppl.
+But in either case, it doesn't matter who needs textrels, it's
+the very fact that they're needed at all.
+
+2006-06-10  Ned Ludd  <solar@gentoo.org>, Mike Frysinger <vapier@gentoo.org>
+
+	* bfd/elflink.c (bfd_elf_final_link): Check all objects for TEXTRELs.
+	* ld/ldmain.c (main): Change textrel warning default to true.
+	* ld/testsuite/lib/ld-lib.exp (default_ld_simple_link): Scrub TEXTREL
+	warnings from ld output.
+
+Original patch from gentoo. Also used by crosstool-ng (binutils-2.20.1a).
