Subject: [PATCH] sparsemem: Shut up unused symbol compiler warnings.
Date: Fri, 1 Jun 2007 13:25:15 +0900 [thread overview]
Message-ID: <20070601042515.GA8628@linux-sh.org> (raw)
__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.
