Classes
struct	ipi_barrier_t

Functions
static void	ipi_barrier_ack (ipi_barrier_t *b)
	Atomically decrement the barrier's ack_count.
static void	ipi_barrier_wait (ipi_barrier_t *b)
	Spin until barrier->ack_count reaches 0.
void	ipi_tlb_shootdown (uint64_t virt)
	Broadcast TLB-shootdown IPI and wait for all CPUs to flush.
void	tlb_shootdown_isr (uint32_t src_cpu)
	ISR for TLB_SHOOTDOWN_VECTOR_BASE + N on remote CPUs (one per possible initiator CPU N — see tlb_shootdown_wrapper0..7 in isr.asm).
void	ipi_panic_halt (void)
	Broadcast halt IPI to all APs on kernel panic.
void	panic_halt_isr (void *frame)
	ISR for PANIC_HALT_VECTOR (52) on APs.
