From 4279777f470d7a5b75e9cf222d18f50e553cd8aa Mon Sep 17 00:00:00 2001
From: "Ricardo M. Correia" <Ricardo.M.Correia@Sun.COM>
Date: Tue, 14 Jul 2009 15:31:03 -0700
Subject: [PATCH] Fixed the zpool and zfs commands returning 'internal error:
 Out of memory.' due to a failure in nvlist_common(). The failure turned out
 to be missing macro definitions for little endian and big endian.
