* gpu: nvgpu: Use timeout retry API in mm_gk20a.cAlex Waterman2016-12-05
| | | | | | | | | | | | | | Use the retry API that is part of the nvgpu timeout API to keep track of retry attempts in the vrious flushing and invalidating operations in the MM code.

* gpu: nvgpu: Add timeout APIAlex Waterman2016-12-05
| | | | | | | | | | | | | | | | | | | | | Add a timeout API to nvgpu since this is a common operation done all across the nvgpu driver. Also add two new directories for this common code: drivers/gpu/nvgpu/common drivers/gpu/nvgpu/include/nvgpu The common directory is for common C code. The include directory is for common include files.
