* gpu: nvgpu: Remove SGL reference from mm_gk20a.cAlex Waterman2017-10-11
| | | | | | | | | | | | | | | | | | | | Remove an SGL reference from the mm_gk20a.c code. This code is common code and as such all linuxisms need to be fixed. It just so happens that this particular function is only used by the CDE code which is only present in Linux. So simply move this function over to the CDE code.

* gpu: nvgpu: memset alloced buffers on freeAlex Waterman2017-10-10
| | | | | | | | | | | | | | | | | | | | | | When freeing kmalloc and vmalloc buffers memset them to zero before freeing them with the kernel APIs. This is only done if CONFIG_NVGPU_TRACK_MEM_USAGE is set since this adds obvious overhead to the driver. However, it is an incredibly useful debug tool, so it's nice to have. This could be done by enabling Linux kernel configs as well, but not all OSes may have such a feature so building it into nvgpu may prove quite useful.
