Subject: linux-next: manual merge of the akpm-current tree with the drm tree

Hi Andrew,

Today's linux-next merge of the akpm-current tree got conflicts in:

  drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c
  drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c

between commits:

  b72cf4fca2bb ("drm/amdgpu: move taking mmap_sem into get_user_pages v2")
  ca666a3c298f ("drm/amdgpu: stop using BO status for user pages")

from the drm tree and commit:

  b7e8af45222b ("mm: remove cold parameter for release_pages")

from the akpm-current 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.
