Subject: linux-next: manual merge of the drm-intel tree with Linus' tree

Hi all,

Today's linux-next merge of the drm-intel tree got a conflict in
drivers/gpu/drm/i915/i915_gem.c between commit 7dc19d5affd7 ("drivers:
convert shrinkers to new count/scan API") from the  tree and commit
e656a6cba0fe ("drm/i915: inline vma_create into lookup_or_create_vma")
from the drm-intel tree.

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

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
