Date: Tue, 24 Apr 2007 19:00:32 +0100 (IST) From: Mel Gorman <mel@....ul.ie> To: akpm@...ux-foundation.org Cc: Mel Gorman <mel@....ul.ie>, linux-kernel@...r.kernel.org, linux-mm@...ck.org, apw@...dowen.org, y-goto@...fujitsu.com, kamezawa.hiroyu@...fujitsu.com Subject: [PATCH 0/2] Fix two boot problems related to ZONE_MOVABLE sizing Following this mail are two fixes related to a boot problem in relation to ZONE_MOVABLE. These are fixes for memory partitioning where kernelcore= is used and is unrelated to grouping pages by mobility. The first patch moves kernelcore= parsing to common code. This avoids an infinite loop that can occur when booting on IA64. As a side-effect, it extends support of kernelcore= to all architectures that use architecture-independent zone-sizing. The second patch aligns ZONE_MOVABLE correctly. The bootmem allocator makes assumptions on the alignment of zones. This can cause pages to be placed on the freelists for the wrong zone resulting in a BUG() later. Aligning ZONE_MOVABLE avoids the problem. They have been successfully boot-tested with and without kernelcore= specified on x86_64, ppc64 and IA64 (where the bug was first triggered). -- Mel Gorman Part-time Phd Student Linux Technology Center University of Limerick IBM Dublin Software Lab - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
