Date: Sat, 8 May 2010 08:17:30 -0700 From: Yinghai Lu <yinghai@...nel.org> To: Ingo Molnar <mingo@...e.hu>, Thomas Gleixner <tglx@...utronix.de>, "H. Peter Anvin" <hpa@...or.com>, Andrew Morton <akpm@...ux-foundation.org> Cc: David Miller <davem@...emloft.net>, Benjamin Herrenschmidt <benh@...nel.crashing.org>, Linus Torvalds <torvalds@...ux-foundation.org>, Johannes Weiner <hannes@...xchg.org>, linux-kernel@...r.kernel.org, linux-arch@...r.kernel.org, Yinghai Lu <yinghai@...nel.org> Subject: [PATCH 12/22] lmb: Add lmb_find_area_node() It can be used to find NODE_DATA for numa. Need to make sure early_node_map[] is filled before it is called, otherwise it will fallback to lmb_find_area(), with node range.
