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

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Andrew,

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

  drivers/gpu/drm/omapdrm/omap_gem.c

between commit:

  cdb0381d2f19 ("drm/omap: gem: Clean up GEM objects memory flags")
(and others following)

from the drm tree and commit:

  c45472f906f4 ("dma-mapping: rename dma_*_writecombine() to dma_*_wc()")

from the akpm-current tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
