lib/interval_tree: fast overlap detection

2017-09-09T01:26:49Z

Allow interval trees to quickly check for overlaps to avoid unnecesary tree lookups in interval_tree_iter_first(). As of this patch, all interval tree flavors will require using a 'rb_root_cached' such that we can have the leftmost node easily available. While most users will make use of this feature, those with special functions (in addition to the generic insert, delete, search calls) will avoid using the cached option as they can do funky things with insertions -- for example, vma_interval_tree_insert_after().

drm/amdgpu: only move VM BOs in the LRU during validation v2

2017-08-17T19:45:57Z

This should save us a bunch of command submission overhead. v2: move the LRU move to the right place to avoid the move for the root BO and handle the shadow BOs as well. This turned out to be a bug fix because the move needs to happen before the kmap. Signed-off-by: Christian König Reviewed-by: Felix Kuehling Acked-by: Chunming Zhou Signed-off-by: Alex Deucher
