    m32r: Exit ei_handler directly for no IRQ case or IPI operations
    If no IRQ request is found in the IRQ check of ei_handler,
    we can exit directly by jumping "restore_all", instead of via
    This modification is also likely effective for IPI operations,
    because scheduler call never happen at the exit of IPIs.
