Subject: linux-next: manual merge of the xen-tip tree with the arm-soc tree
Date: Mon, 8 Dec 2014 18:49:08 +1100 [thread overview]
Message-ID: <20141208184908.27bfd605@canb.auug.org.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 2472 bytes --]
Hi all,
Today's linux-next merge of the xen-tip tree got a conflict in
arch/arm/include/asm/dma-mapping.h between commits a3a60f81ee6f
("dma-mapping: replace set_arch_dma_coherent_ops with
arch_setup_dma_ops") and 4bb25789ed28 ("arm: dma-mapping: plumb our
iommu mapping ops into arch_setup_dma_ops") from the arm-soc tree and
commit 3d5391ac6f5e ("arm: introduce is_device_dma_coherent") from the
xen-tip tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
I also neede this merge fix patch:
