Hi all,

After merging the final tree, today's linux-next build
(powerpc64 allnoconfig) failed like this:

arch/powerpc/kernel/built-in.o: In function `.sys_call_table':
(.text+0x8d48): undefined reference to `.compat_sys_recv'

Caused by commit 86250b9d12caa1a3dee12a7cf638b7dd70eaadb6 ("powerpc: Wire
up direct socket system calls").

I have applied this patch for today:

Since compat_sys_recv is an optionl syscall if the kernel is compiled
without networking we need a cond_syscall defined for it since it is now
wired up directly on PowerPC.

Other architectures that wire up the socket calls directly as syscalls
do not run into this issue either because they don't have to deal with
the 32bit compat versions of the syscalls or just don't wire up that
particular compat syscall directly.
