CPU/LLVM-only build (USE_CUDA=OFF, USE_LLVM=ON), the build mode upstream documents but never exercises in its own release CI (which only ever ships CUDA/Metal wheels). Two patches: one excludes the optional torch-c-dlpack-ext dependency on riscv64, where it has no wheel and upstream itself documents it as a soft, JIT-fallback dependency; the other caps the unbounded cython build requirement below 3.3, whose newly added Limited-API-3.9-minimum check breaks tilelang's cp38 Limited API target on any platform, not just riscv64.

Patches
0001-exclude-torch-c-dlpack-ext-from-the-riscv64-depende.patch- Inappropriate. torch-c-dlpack-ext (optional, marker-gated) has no riscv64 wheel anywhere; upstream calls it a soft, JIT-fallback dependency. Reproduces on any arch lacking a wheel for it, not riscv64-only.Built on cp312; import succeeds, prints version.
