* gpu: nvgpu: remove sync_fence dependencies from fence_gk20aDebarshi Dutta2018-05-10
| | | | | | | | | | | | | | | | | Replaced all instances of sync_fence in gk20a_fence* code with nvgpu_os_fence. Added the API install_fence for the nvgpu_os_fence abstraction. sync_fence mechanism and its dependencies are completely removed from the fence_gk20a methods. Due to the recent os_fence changes and the changes to fence_gk20a, we can finally get rid of all the CONFIG_SYNCS present in the submit path.
