Re: sys_recvmmsg: wire up or not?

It's also rather inconsistent with the last socket call that was added, sys_accept4.
Some architectures that normally define socket calls (parisc, sh) are missing both
accept4 and recvmmsg, while others that don't have recvmsg now get recvmmsg.

In particular, i386 has recvmmsg now, which caused the warning that you saw.
I guess that one should be removed, and maybe we need a better logic for
determining which syscalls you actually want. Deriving it from asm-generic/unistd.h
instead of arch/x86/include/asm/unistd_32.h is probably better, but would still
give the wrong answer for multiplexed system calls like socketcall or ipc on 
existing architectures.

Anything happening here ? We're getting that warning on ppc too despite
the fact that we use socketcall like x86... Should checksyscall be made
smarter or the syscall just removed from x86 ? :-)

Cheers,
Ben.
