mq_timedreceive

receive a message from a message queue

sys_mq_timedreceive_time32(mqd_t mqdes, char *u_msg_ptr, unsigned int msg_len, unsigned int *u_msg_prio, const struct old_timespec32 *u_abs_timeout)

register	value
`v0`	6237, the syscall number
`a0`	mqd_t mqdes
`a1`	char *u_msg_ptr
`a2`	unsigned int msg_len
`a3`	unsigned int *u_msg_prio
`a4`	const struct old_timespec32 *u_abs_timeout
`v0`	the return value

Then run syscall to enter the kernel.

Same syscall on other architectures
