Looks Good, and one suggestion for runtime exception:
undefined symbol: _Z16gptq_marlin_gemmRN2at6TensorES1_S1_S1_S1_S1_lS0_lllib

I sincerely apologize. This patch only addresses compilation issues. Since vLLMMarlin wasn't supported, I had commented it out in my local environment. Alternatively, we could move the import vLLMMarlin statement to the actual usage location. I'll update the patch shortly.

@kevin-t-tang Just updated – could you please review? Thanks!
