[merged mm-nonmm-stable] net-unexport-csum_and_copy_fromto_user.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: net: unexport csum_and_copy_{from,to}_user
has been removed from the -mm tree.  Its filename was
     net-unexport-csum_and_copy_fromto_user.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

------------------------------------------------------
From: Christoph Hellwig <hch@lst.de>
Subject: net: unexport csum_and_copy_{from,to}_user

csum_and_copy_from_user and csum_and_copy_to_user are exported by a few
architectures, but not actually used in modular code.  Drop the exports.
