Subject: linux-next: manual merge of the drm-misc tree with the drm and drm-intel trees

Hi all,

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

  drivers/gpu/drm/amd/amdgpu/amdgpu_object.c
  drivers/gpu/drm/i915/i915_vma.c
  drivers/gpu/drm/i915/i915_gem_batch_pool.c
  drivers/gpu/drm/i915/gem/i915_gem_object.c
  drivers/gpu/drm/i915/gt/intel_engine_pool.c

between commits:

  a93615f900bd ("drm/i915: Throw away the active object retirement complexity")
  12c255b5dad1 ("drm/i915: Provide an i915_active.acquire callback")
  cd2a4eaf8c79 ("drm/i915: Report resv_obj allocation failure")
  b40d73784ffc ("drm/i915: Replace struct_mutex for batch pool serialisation")
  ab2f7a5c18b5 ("drm/amdgpu: Implement VRAM wipe on release")
  0c159ffef628 ("drm/i915/gem: Defer obj->base.resv fini until RCU callback")

from the drm and drm-intel trees and commit:

  52791eeec1d9 ("dma-buf: rename reservation_object to dma_resv")

from the drm-misc tree.

I fixed it up (see below and I added 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.
