This pull request includes:

  • Update stdarch dependency to include ratified RISC-V supervisor and hypervisor instruction intrinsics which is useful in Rust kernel development
  • Add macro is_riscv_feature_detected!
  • Modify impl of core::hint::spin_loop to comply with latest version of core::arch

After this update, users may now develop RISC-V kernels and user applications more freely.
