Subject: [PATCH] powerpc: Wire up direct socket system calls

From: Ian Munsie <imunsie@....ibm.com>

This patch wires up the various socket system calls on PowerPC so that
userspace can call them directly, rather than by going through the
multiplexed socketcall system call.

Signed-off-by: Ian Munsie <imunsie@....ibm.com>
