drm/amdgpu: call amdgpu_vm_prt_fini before deleting the root PD

2019-10-25T20:47:07+00:00

amdgpu_vm_prt_fini uses "vm->root.base.bo" so it must still be valid when
we call it.

drm/ttm: remove pointers to globals

2019-10-25T09:40:51+00:00

As the name says global memory and bo accounting is global. So it doesn't
make to much sense having pointers to global structures all around the code.

drm/amdgpu: fix uninitialized variable pasid_mapping_needed

2019-10-04T13:53:14+00:00

The boolean variable pasid_mapping_needed is not initialized and
there are code paths that do not assign it any value before it is
is read later.  Fix this by initializing pasid_mapping_needed to
false.
