I applied the following 4 patches :

0001-drm-amdgpu-WIP-Explicitly-add-a-flexible-array-at-th.patch
0002-drm-amdgpu-WIP-Remove-a-redundant-sanity-check.patch
0003-drm-amdgpu-WIP-Use-kvzalloc-to-simplify-code.patch
0004-drm-amdgpu-WIP-Remove-amdgpu_bo_list_array_entry.patch

and all IGT tests were successful.
