When building with CONFIG_BINFMT_MISC=m linux-next (next-20110728) breaks: ERROR: "copy_from_user_overflow" [fs/binfmt_misc.ko] undefined! The issue was introduced by commit ab3b49d018924085e5d949c1af53fae0da9a8d94: "The help text for this config is duplicated across the x86, parisc, and s390 Kconfig.debug files." After reporting the issue to linux-next/LKML mailing-lists, Stephen Boyd told me he had already sent a fix [1] which should be folded into [2]. Unfortunately, Stephen's fixup didn't get into Andrew's mmotm-tree and find its way from there to linux-next. Tested on x86_64 (Randy) and i386 (Sedat).
