[PATCH 0/4] Use memdup_user & co where applicable

[Tvrtko Ursulin]

Replace some allocate + copy_from_user patterns with dedicated helpers.

This shrinks the source code and is also good for security due SLAB bucket
separation between the kernel and uapi.

Tvrtko Ursulin (4):
  drm/amdgpu: Use vmemdup_array_user in
    amdgpu_bo_create_list_entry_array
  drm/amdgpu: Use memdup_array_user in amdgpu_cs_wait_fences_ioctl
  drm/amdgpu: Use (v)memdup_array_user in amdgpu_cs_pass1
  drm/amdgpu: Use memdup_user in ta_if_load_debugfs_write
