Subject: linux-next: manual merge of the akpm-current tree with the arm tree

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in:

  arch/arm/mm/dma-mapping.c

between commit:

  f12708965069 ("ARM: 8561/3: dma-mapping: Don't use outer_flush_range when the L2C is coherent")

from the arm tree and patch:

   "dma-mapping: remove dma_get_attr"

from the akpm-current tree.

I fixed it up (see below) 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.

Cheers,
Stephen Rothwell
