From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Rothwell Subject: linux-next: manual merge of the akpm-current tree with the drm tree Date: Mon, 24 Jun 2019 20:49:08 +1000 Message-ID: <20190624204908.64a33862@canb.auug.org.au> Mime-Version: 1.0 Content-Type: multipart/signed; micalg=pgp-sha256; boundary="Sig_/smpkyf3iKW.KYSxeqEWRcnh"; protocol="application/pgp-signature" Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Andrew Morton , Dave Airlie , DRI Cc: Linux Next Mailing List , Linux Kernel Mailing List , Thomas Hellstrom , Anshuman Khandual List-Id: dri-devel@lists.freedesktop.org --Sig_/smpkyf3iKW.KYSxeqEWRcnh Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable Hi all, Today's linux-next merge of the akpm-current tree got a conflict in: mm/memory.c between commit: 29875a52915e ("mm: Add an apply_to_pfn_range interface") from the drm tree and commit: e972cea08fb3 ("mm/pgtable: drop pgtable_t variable from pte_fn_t function= s") from the akpm-current tree. I fixed it up (see below my signature, then added the following merge resolution patch as well) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts.
