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
`g1`	275, the syscall number
`o0`	mqd_t mqdes
`o1`	const char *u_msg_ptr
`o2`	unsigned int msg_len
`o3`	unsigned int msg_prio
`o4`	const struct old_timespec32 *u_abs_timeout
`o0`	the return value

Then run t 0x10 to enter the kernel.

Same syscall on other architectures
