2017-08-29drm/amdgpu: Fix huge page updates with CPUFelix Kuehling1-1/+15
Correctly detect system memory mappings when using CPU and don't use huge pages for them.

2017-08-24drm/amdgpu: fix and cleanup shadow handlingChristian König1-8/+0
Set the shadow flag on the shadow and not the parent, always bind shadow BOs during allocation instead of manually, use the reservation_object wrappers to grab the lock. This fixes a couple of issues with binding the shadow BOs as well as correctly evicting them when memory becomes tight.
