 * SYSCALL_TRAP_HANDLE_INIT - system call trap magic number
 *
 * On VxSim, the system call infrastucture is based on a mechanism to directly
 * call kernel services from RTP via the syscallTrapHandle() routine.
 * Since the RTP does not have access to syscallTrapHandle() routine, each RTP
 * contains a function pointer _func_syscallTrapHandle which is initialized to
 * an invalid address: SYSCALL_TRAP_HANDLE_INIT. On the first system call
 * performed by the RTP, an exception will be generated, the exception
 * handling will invoke syscallTrapHandlerInit() if installed, and
 * syscallTrapHandlerInit() will fix _func_syscallTrapHandle to point to
 * syscallTrapHandle().
