recvmmsg

receive multiple messages on a socket

compat_sys_recvmmsg_time64(int fd, struct mmsghdr *msg, unsigned int vlen, unsigned flags, struct __kernel_timespec *timeout)

register	value
`rax`	1073742361, the syscall number
`rdi`	int fd
`rsi`	struct mmsghdr *msg
`rdx`	unsigned int vlen
`r10`	unsigned flags
`r8`	struct __kernel_timespec *timeout
`rax`	the return value

Then run syscall to enter the kernel.

Same syscall on other architectures
