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 ? :-)

I think it's better to trap directly to the system call rather
than going through yet another demultiplexer.

I severely regretted using sys_socketcall initially on sparc32
because it added a few microseconds to socket syscall latency
(cpus back then were slow :-)
