When building for 32-bit ARM, there is a link time error because of a 64-bit division: ld.lld: error: undefined symbol: __aeabi_uldivmod >>> referenced by spectrum_buffers.c >>> net/ethernet/mellanox/mlxsw/spectrum_buffers.o:(mlxsw_sp_buffers_init) in archive drivers/built-in.a >>> did you mean: __aeabi_uidivmod >>> defined in: arch/arm/lib/lib.a(lib1funcs.o Avoid this by using div_u64, which is designed to avoid this problem.
