Subject: [PATCH v5 00/10] drm/amdgpu: preparation patchs for the use all SDMA instances series

This series is a subset of the "use all SDMA instances" series.
It starts at the first modified patch and ends at the last patch
before the drm/ttm patch that got merged through drm-misc-next.

The main changes from v4 are:
* rebased on top of amd-staging-drm-next which allows to use
  amdgpu_gtt_mgr_alloc_entries
* fixed a bug in kfd_migrate.c (patch 2)

v4:
