drm/vmwgfx: dma-buf: Constify ttm_place structures.

2017-07-18T06:40:57+00:00

ttm_place are not supposed to change at runtime. All functions
working with ttm_place provided by  work
with const ttm_place. So mark the non-const structs as const.

drm/ttm: revert "implement LRU add callbacks v2"

drm/ttm: add evict parameter to ttm_bo_driver::move_notify

2017-01-27T16:13:15+00:00

Ensure that the driver can listen to evictions even when they don't take the
path through ttm_bo_driver::move.

This is crucial for amdgpu, which relies on an eviction counter to skip
re-binding page tables when possible.
