This is a note to let you know that I have just added a patch titled tilepro: work around module link error with gcc 4.7 to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From ea8c1cc91a7c1bfd5f3482c334fd985a45f30e11 Mon Sep 17 00:00:00 2001 From: Chris Metcalf <cmetcalf@tilera.com> Date: Sat, 15 Jun 2013 16:47:47 -0400 Subject: [PATCH] tilepro: work around module link error with gcc 4.7 commit 3cb3f839d306443f3d1e79b0bde1a2ad2c12b555 upstream. gcc 4.7.x is emitting calls to __ffsdi2 where previously it used to inline the appropriate ctz instructions. While this needs to be fixed in gcc, it's also easy to avoid having it cause build failures when building with those compilers by exporting __ffsdi2 to modules.
