drm/amdgpu: Revert "remove the userptr rmn->lock"

2016-03-21T15:52:14Z

This reverts commit c02196834456f2d5fad334088b70e98ce4967c34. In the meantime we moved get_user_pages() outside of the reservation lock, so that shouldn't be an issue any more Signed-off-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Don't call interval_tree_remove in amdgpu_mn_destroy

2016-02-17T21:10:56Z

rbtree_postorder_for_each_entry_safe can skip over some entries if the tree is rebalanced in interval_tree_remove. interval_tree_remove is also redundant when the tree is just about to be freed. Signed-off-by: Felix Kuehling Reviewed-by: Christian König

drm/amdgpu: Fix race condition in amdgpu_mn_unregister

2016-02-17T21:10:42Z

Exchange locking order of adev->mn_lock and mm_sem, so that rmn->mm->mmap_sem can be taken safely, protected by adev->mn_lock, when amdgpu_mn_destroy runs concurrently. Signed-off-by: Felix Kuehling Reviewed-by: Christian König

drm/amdgpu: Fix race condition in MMU notifier release

2016-02-16T22:17:14Z

The release notifier can get called a second time from mmu_notifier_unregister depending on a race between __mmu_notifier_release and amdgpu_mn_destroy. Use mmu_notifier_unregister_no_release to avoid this. Signed-off-by: Felix Kuehling Reviewed-by: Christian König

drm/amdgpu: remove the userptr rmn->lock

2016-02-12T20:32:07Z

Avoid a lock inversion problem by just using the mmap_sem to protect the entries of the intervall tree. Signed-off-by: Christian König Reviewed-by: Felix Kuehling

drm/amdgpu: fix issue with overlapping userptrs

2016-02-10T19:16:43Z

Otherwise we could try to evict overlapping userptr BOs in get_user_pages(), leading to a possible circular locking dependency. Signed-off-by: Christian König Acked-by: Alex Deucher
