DISPATCH_FLOATING_TYPES was defined in xllm/core/kernels/cuda/utils.h which was pulled in via cuda_ops_api.h → utils.h. Since cuda_ops_api.h was removed (glog dependency), the macro was missing. Now defined in device_utils.cuh with include guard, available to all kernel files: norm.cu, activation.cu, rope.cu, block_copy.cu, reshape_paged_cache.cu
