Subject: linux-next: manual merge of the dma-mapping tree with the kbuild
 tree

Hi all,

Today's linux-next merge of the dma-mapping tree got a conflict in:

  arch/nios2/Kconfig

between commit:

  17c46a6aff5c ("kconfig: remove duplicate SWAP symbol defintions")

from the kbuild tree and commit:

  25622e045a6a ("nios2: use generic dma_noncoherent_ops")

from the dma-mapping 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
