From 8bc1f91e1f0e977fb95b11d8fa686f5091888110 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Thu, 24 Feb 2011 14:43:06 +0100 Subject: bootmem: Move __alloc_memory_core_early() to nobootmem.c Now that bootmem.c and nobootmem.c are separate, there's no reason to define __alloc_memory_core_early(), which is used only by nobootmem, inside #ifdef in page_alloc.c. Move it to nobootmem.c and make it static. This patch doesn't introduce any behavior change. -tj: Updated commit description.
