Functions
auto	arch::s390x::cpu::sigp::default_backoff (u64 timeout_tod) noexcept -> sigp_backoff
	Build a sigp_backoff with default parameters.
auto	arch::s390x::cpu::sigp::issue (u16 addr, u8 order, u64 parm) -> sigp_result
	Issue a SIGP (Signal Processor) instruction.
auto	arch::s390x::cpu::sigp::issue_bounded (u16 cpu_addr, u8 order, u32 parm) noexcept -> sigp_result
	Issue SIGP with exponential backoff until the target CPU is no longer busy (CC != 2) or the deadline expires.
auto	arch::s390x::cpu::sigp::issue_bounded (u16 cpu_addr, u8 order, u32 parm, sigp_backoff &backoff) noexcept -> sigp_result
	Issue SIGP with exponential backoff until the target CPU is no longer busy (CC != 2) or the deadline expires.
auto	arch::s390x::cpu::sigp::wait_cpu_stopped (u16 cpu_addr) noexcept -> sigp_result
	Wait until a CPU is stopped, with check-stop recovery.
