-hip: port the turboquant CUDA additions that ggml's HIP shim doesn't cover
-
-The turboquant fork adds/modifies a few ggml-cuda.cu spots with CUDA APIs
-that ggml's HIP (and MUSA) compatibility layer does not provide, breaking
-the -gpu-rocm-hipblas-turboquant build:
-
-  1. ggml_cuda_copy2d_across_devices() (host-staged cross-device copy for
-     split mul_mat output) uses the CUDA 3D-peer copy APIs
-     cudaMemcpy3DPeerParms / make_cudaPitchedPtr / make_cudaExtent /
-     cudaMemcpy3DPeerAsync. HIP genuinely does not support these (see the
-     fork's own comment "HIP does not support cudaMemcpy3DPeerAsync"), so
-     guard the peer fast path with #if !defined(GGML_USE_HIP) &&
-     !defined(GGML_USE_MUSA) -- matching how the fork already guards the
-     same API for the sibling 2D copy -- and fall through to the existing
-     cudaMemcpyAsync staging fallback below (functionally identical,
-     slightly slower on multi-GPU ROCm).
-
-  2. ggml_backend_cuda_device_event_new() creates its event with plain
-     cudaEventCreate, which ggml's HIP shim does not alias (it only aliases
-     cudaEventCreateWithFlags). Use cudaEventCreateWithFlags(..., 
-     cudaEventDisableTiming) -- exactly what the rest of this file already
-     does (cf. lines ~1034, ~3461) and HIP-safe.
-
-CUDA builds are unaffected. Drop the relevant hunk once the fork HIP-ports
-these; apply-patches.sh fails fast if an anchor goes stale.
