As you said, I copied sha512block from for
gcn and for others
and I included

#if !gpu_nvidia(DEVICE_INFO) || nvidia_sm_5x(DEVICE_INFO)
#elif gpu_nvidia(DEVICE_INFO)
#define OLD_NVIDIA

I don't use USE_BITSELECT or OLD_NVIDIA but it's faster on my laptop

and I resigned from vectors, was slower with them
