Subject: linux-next: manual merge of the drm-intel tree with the
 drm-intel-fixes 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 067556084a0e ("drm/i915:
Correct obj->mm_list link to dev_priv->dev_priv->mm.inactive_list") from
the drm-intel-fixes tree and commit 5cef07e16283 ("drm/i915: Move
active/inactive lists to new mm") from the drm-intel tree.

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

Cheers,
