Subject: linux-next: manual merge of the drm tree with the drm-misc-fixes
 tree

Hi all,

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

  drivers/gpu/drm/amd/amdgpu/amdgpu_job.c

between commit:

  b09d6acba1d9 ("drm/amdgpu: handle gang submit before VMID")

from the drm-misc-fixes tree and commits:

  c5093cddf56b ("drm/amdgpu: drop the fence argument from amdgpu_vmid_grab")
  940ca22b7ea9 ("drm/amdgpu: drop amdgpu_sync from amdgpu_vmid_grab v2")
  1b2d5eda5ad7 ("drm/amdgpu: move explicit sync check into the CS")
  1728baa7e4e6 ("drm/amdgpu: use scheduler dependencies for CS")

from the drm tree.

I fixed it up (see below) 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.
