03e9dee11d drm/amdgpu: Fix compute VM BO params after rebase v2
The intent of two commits was lost in the last rebase:

810955b drm/amdgpu: Fix acquiring VM on large-BAR systems
b5d21aa drm/amdgpu: Don't use shadow BO for compute context

This commit restores the original behaviour:
* Don't set AMDGPU_GEM_CREATE_NO_CPU_ACCESS for page directories
  to allow them to be reused for compute VMs
* Don't create shadow BOs for page tables in compute VMs

v2: move more logic into amdgpu_vm_bo_param

cae50a43b9 drm/amd/display: use link type to decide stream enc acquisition
[Why]
Virtual sink is used when set mode happens on a disconnected display
to allow the mode set to proceed. This did not work with MST because
the logic for acquiring stream encoder uses stream signal to determine
the special handling is required, and stream signal is virtual instead
of DP in this case.

[How]
Use link type to decide instead.

a487411a64 drm/amd/display: Use DRM helper for best_encoder
[Why]
Our implementation is functionally identical to DRM's

Note that instead of checking if the provided id is 0, the helper
follows through with the mode object search. However, It will still
return NULL, since 0 is not a valid object id, and missed searches
will return NULL.

Remove our implementation, and replace it with
drm_atomic_helper_best_encoder.

dcaaff4eed drm/amdgpu: remove redundant memset
kvmalloc_array uses __GFP_ZERO flag ensures that the returned address
is zeroed already, memset it to zero again afterwards is unnecessary,
and in this case buggy because we only clear the first entry.

25eef4214a drm/ttm: Initialize local lists in ttm_bo_bulk_move_helper
The first parameter of list_cut_position() must point to an initialized
list.

Noticed thanks to KASAN pointing out something's fishy here.

d78c1fa0c9 Revert "drm/amdgpu: move PD/PT bos on LRU again"
This reverts commit 31625ccae4464b61ec8cdb9740df848bbc857a5b.

It triggered various badness on my development machine when running the
piglit gpu profile with radeonsi on Bonaire, looks like memory
corruption due to insufficiently protected list manipulations.
