Ettore Di Giacinto 9787bee48b fix(buun-llama-cpp): shim cudaMemcpy{To,From}Symbol + WARP_SIZE on fwht128 shuffles ... Two more hipblas-only build failures in buun's fattn.cu, fixed under the same patches/ infrastructure: 1. cudaMemcpyToSymbol / cudaMemcpyFromSymbol — buun's Q² calibration + TCQ codebook upload paths call the symbol variants of cudaMemcpy. ggml/src/ggml-cuda/vendors/hip.h aliases every other cudaMemcpy* name (cudaMemcpy, cudaMemcpyAsync, cudaMemcpy2DAsync, …) but the symbol pair was never added. 15+ "use of undeclared identifier" errors across fattn.cu lines 40, 54, 74-76, 94, 100-101, 371, 883, 905, 954, 976, 1449, 1463. Add the two missing aliases alongside the existing memcpy block. 2. __shfl_xor_sync fwht128 calls — same 3-arg omission pattern as the earlier argmax top-K fix. Lines 512 (ggml_cuda_fwht128 intra-warp butterfly) and 536 (fwht128_store_half neighbor fetch) drop the width argument that hip.h:33 requires. Add WARP_SIZE.
