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
`r11`	182, the syscall number
`r3`	mqd_t mqdes
`r4`	const char *u_msg_ptr
`r5`	unsigned int msg_len
`r6`	unsigned int msg_prio
`r7`	const struct old_timespec32 *u_abs_timeout
`r11`	the return value

Then run l.sys 1 to enter the kernel.

Same syscall on other architectures
