From e782ab421bbba1912c87934bd0e8998630736418 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Thu, 24 Feb 2011 14:43:06 +0100 Subject: bootmem: Move contig_page_data definition to bootmem.c/nobootmem.c Now that bootmem.c and nobootmem.c are separate, it's cleaner to define contig_page_data in each file than in page_alloc.c with #ifdef. Move it. This patch doesn't introduce any behavior change. -v2: According to Andrew, fixed the struct layout. -tj: Updated commit description.
