+Subject: [PATCH] Allow importing on linux riscv64
+
+lib3mf/__init__.py raises OSError for any Linux machine type other than
+x86_64 and aarch64, before Lib3MF.py ever tries to load lib3mf.so. The
+library itself is built from source for the host architecture, so the
+allowlist is the only thing that stops a riscv64 wheel from importing.
+
+Upstream-Status: To upstream [not yet submitted; python-wheels does not open issues/PRs on third-party repos]
