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:

From: Stephen Rothwell <redacted>
Date: Fri, 3 Sep 2010 13:19:04 +1000
Subject: [PATCH] powerpc: define a compat_sys_recv cond_syscall
