Last few updates for 4.16:
- Misc fixes for amdgpu
- Enable swapout for reserved BOs during allocation for ttm
- Misc cleanups for ttm

* 'drm-next-4.16' of git://people.freedesktop.org/~agd5f/linux: (24 commits)

  drm/ttm: enable swapout for reserved BOs during allocation
  drm/ttm: add new function to check if bo is allowable to evict or swapout
  drm/ttm: use an operation ctx for ttm_tt_bind

  drm/ttm: use an operation ctx for ttm_mem_global_alloc_page
  drm/ttm: use an operation ctx for ttm_mem_global_alloc
  drm/ttm: call ttm_bo_swapout directly when ttm shrink
  drm/vmwgfx: remove the default io_mem_pfn set
  drm/virtio: remove the default io_mem_pfn set
