Use the LRU walker for eviction. This helps removing a lot of code with weird locking semantics. The functionality is slightly changed so that when trylocked buffer objects are exhausted, we continue to interleave walks with ticket-locks while there is still progress made. The list walks are not restarted in-between evictions. Also provide a separate ttm_bo_evict_first() function for its single user. The context of that user allows sleeping dma_resv locks. v6: - Various cleanups suggested by Matthew Brost. - Fix error return code of ttm_bo_evict_first(). (Matthew Brost) - Fix an error check that was inverted. (Matthew Brost) v7: - Use s64 rather than long (Christian König) - Early ttm_resource_cursor_fini() in ttm_bo_evict_first(). - Simplify check for bo_moved in ttm_bo_evict_first(). (Christian König) - Don't evict pinned bos.
