I'm not sure actually why it's called "Socketcall". Is that an
offset in the syscall numbering?

In any case, TARGET_NR_sendmmsg and TARGET_NR_recvmmsg are not
defined here:

According to the kernel sources, recvmmsg is defined as 371 and sendmmsg
as 372:

And hence once should add:

#define TARGET_NR_recvmmsg              371
#define TARGET_NR_sendmmsg              372

The implementation can be found here:

What about the other syscalls 349 through 374, btw?
