Message-ID: <20070601042515.GA8628@linux-sh.org>
Date:	Fri, 1 Jun 2007 13:25:15 +0900

Cc:	linux-mm@...ck.org, linux-kernel@...r.kernel.org
Subject: [PATCH] sparsemem: Shut up unused symbol compiler warnings.

__kmalloc_section_memmap()/__kfree_section_memmap() and friends are only
used by the memory hotplug code. Move these in to the existing
CONFIG_MEMORY_HOTPLUG block.

Signed-off-by: Paul Mundt <lethal@...ux-sh.org>
