Functions
void	trampoline_init (void)
	Initializes the trampoline by copying the trampoline code to its designated memory location.
void	trampoline_deinit (void)
	Deinitializes the trampoline by restoring the original contents of the trampoline memory location.
void	trampoline_send_startup_ipi (cpu_t *cpu, lapic_id_t lapicId)
	Sends the startup IPI to a CPU to start it up.
uint64_t	trampoline_wait_ready (clock_t timeout)
	Waits for the currently starting CPU to signal that it is ready.
static void	trampoline_after_jump (void)
void	trampoline_c_entry (cpu_t *cpu)
	After the trampoline is done with basic initialization, it calls this C entry point to continue CPU initialization.

Variables
static void *	backupBuffer
static void *	trampolineStack
static atomic_bool	cpuReadyFlag = ATOMIC_VAR_INIT(false)
