  # Idle-hook backend, covering every architecture that provides the idle hooks
  # (ARCH_HAS_CPU_IDLE_HOOKS). This spans both ways of closing the idle window:
  # Arm Cortex-M, Arm64 and RISC-V close it in the idle-exit hook, while x86 and
  # Xtensa wait with interrupts enabled and close it at ISR entry.
