DEBUG_LOCKS_WARN_ON(sem->owner != ((struct task_struct *)(1UL << 0)))

[Michel Dänzer]

I've been occasionally getting the debugging warnings seen in the
attached kernel log excerpt. Only for piglit amd_pinned_memory and for
libdrm amdgpu_test, so I suspect it's pointing at a userptr related
issue. Christian, any ideas?
