If anyone has any objections, please let me know. ------------------ From: Chris Metcalf 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.
