* gpu: nvgpu: Move allocators to common/mm/Alex Waterman2017-01-09
| | | | | | | | | | | | | | | | | | | Move the GPU allocators to common/mm/ since the allocators are common code across all GPUs. Also rename the allocator code to move away from gk20a_ prefixed structs and functions. This caused one issue with the nvgpu_alloc() and nvgpu_free() functions. There was a function for allocating either with kmalloc() or vmalloc() depending on the size of the allocation. Those have now been renamed to nvgpu_kalloc() and nvgpu_kfree().
