Subject: [PATCH -next] usercopy: Fixup patch to commit 4df97ff66a102a89ecfa2f88051e30bdd54ad864
Date: Fri, 29 Jul 2011 20:58:12 +0200 [thread overview]
Message-ID: <1311965892-17026-1-git-send-email-sedat.dilek@gmail.com> (raw)
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).
