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

Hi all,

Today's linux-next merge of the drm-intel-gt tree got a conflict in:

  drivers/gpu/drm/i915/i915_drv.h

between commit:

  2ef97818d3aa ("drm/i915: split out i915_gem_evict.h from i915_drv.h")

from the drm-intel tree and commit:

  7e00897be8bf ("drm/i915: Add object locking to i915_gem_evict_for_node and i915_gem_evict_something, v2.")

from the drm-intel-gt tree.

I fixed it up (I used the former and adde the following merge fix patch)
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.
