mq_timedsend

send a message to a message queue

sys_mq_timedsend_time32(mqd_t mqdes, const char *u_msg_ptr, unsigned int msg_len, unsigned int msg_prio, const struct old_timespec32 *u_abs_timeout)

register	value
`d0`	273, the syscall number
`d1`	mqd_t mqdes
`d2`	const char *u_msg_ptr
`d3`	unsigned int msg_len
`d4`	unsigned int msg_prio
`d5`	const struct old_timespec32 *u_abs_timeout
`d0`	the return value

Then run trap #0 to enter the kernel.

Same syscall on other architectures
