Date: Wed, 20 Mar 2013 14:03:27 -0400 From: Johannes Weiner <hannes@...xchg.org> To: x86@...nel.org, Andrew Morton <akpm@...ux-foundation.org> Cc: Ben Hutchings <ben@...adent.org.uk>, linux-mm@...ck.org, linux-arch@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [patch 0/5] sparse-vmemmap: hotplug fixes & cleanups Hotplug can happen at times when the memory situation is less than perfect to allocate huge pages for the vmemmap. This series makes the allocation try harder in patch #1. The remaining patches allow x86-64 to fall back to regular pages as a last resort before the hotplug event fails completely. As a prerequisite to this, the arch interface to sparse is cleaned up a little, which should also enable other architectures to easily mix huge and regular pages in the vmemmap. arch/arm64/mm/mmu.c | 13 +++++-------- arch/ia64/mm/discontig.c | 7 +++---- arch/powerpc/mm/init_64.c | 11 +++-------- arch/s390/mm/vmem.c | 13 +++++-------- arch/sparc/mm/init_64.c | 7 +++---- arch/x86/mm/init_64.c | 68 ++++++++++++++++++++++++++++++++------------------------------------ include/linux/mm.h | 8 ++++---- mm/sparse-vmemmap.c | 27 +++++++++++++++++---------- mm/sparse.c | 10 ++++++++-- 9 files changed, 80 insertions(+), 84 deletions(-) -- 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/
