+Alexandre Oliva <oliva@lsd.ic.unicamp.br> sent me a patch:
+
+"I see you ran into the same problem I did in brcmfmac.  I wasn't sure a
+build with compat-wireless would run into the same problem I did without
+it and with Linux-libre.
+
+It's an issue brought about by GCC 4.7's partial-inlining, that ends up
+splitting the udelay function just at the wrong spot, in such a way that
+some sanity checks for constants fails, and we end up calling
+bad_udelay.
+
+This patch fixes the problem.  Feel free to push it upstream if it makes
+sense to you."
