Subject: [ 37/53] ia64: Add accept4() syscall

3.2.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Émeric Maschino <emeric.maschino@...il.com>

commit 65cc21b4523e94d5640542a818748cd3be8cd6b4 upstream.

While debugging udev > 170 failure on Debian Wheezy
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=648325), it appears
that the issue was in fact due to missing accept4() in ia64.

This patch simply adds accept4() to ia64.
