Subject: [PATCH 2/2] move unneeded data to initdata section

From: "Denis V. Lunev" <[email-masked]>
Date: Wed, 7 Nov 2007 15:01:00 +0300

This patch reverts Eric's commit 2b008b0a8e96b726c603c5e1a5a7a509b5f61e35

It diets .text & .data section of the kernel if CONFIG_NET_NS is not set.
This is safe after list operations cleanup.
