Date: Tue, 3 Dec 2013 08:51:47 +0000 From: Mel Gorman <mgorman@...e.de> To: Alex Thorlton <athorlton@....com> Cc: Rik van Riel <riel@...hat.com>, Linux-MM <linux-mm@...ck.org>, LKML <linux-kernel@...r.kernel.org>, Mel Gorman <mgorman@...e.de> Subject: [PATCH 00/14] NUMA balancing segmentation faults candidate fix on large machines Alex Thorlton reported segementation faults when NUMA balancing is enabled on large machines. There is no obvious explanation from the console what the problem is so this series is based on code review. The series is against 3.12. In the event it addresses the problem the patches will need to be forward-ported and retested. The series is not against the latest mainline as changes to PTE scan rates may mask the bug. arch/x86/mm/gup.c | 13 ++++ include/linux/hugetlb.h | 10 ++-- include/linux/migrate.h | 27 ++++++++- kernel/sched/fair.c | 16 ++++- mm/huge_memory.c | 58 ++++++++++++++---- mm/hugetlb.c | 51 ++++++---------- mm/memory.c | 93 ++--------------------------- mm/mempolicy.c | 2 + mm/migrate.c | 155 ++++++++++++++++++++++++++++++++++++++++++++---- mm/mprotect.c | 50 ++++------------ mm/pgtable-generic.c | 3 + mm/swap.c | 143 +++++++++++++++++++++++++------------------- 12 files changed, 371 insertions(+), 250 deletions(-) -- 1.8.4 -- 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/
