The original goal of this patchset is to fix the bug reported by https://bugzilla.kernel.org/show_bug.cgi?id=53501 Now it has also been expanded to reduce common code used by memory initializion. This is the third part, previous two patch sets could be accessed at: http://marc.info/?l=linux-mm&m=136289696323825&w=2 http://marc.info/?l=linux-mm&m=136290291524901&w=2 This patchset applies to git://git.cmpxchg.org/linux-mmotm.git v3.9-rc8-mmotm-2013-04-25-16-24 V2->V4: 1) rebase to git://git.cmpxchg.org/linux-mmotm.git 2) fix some build warnings and other minor bugs of previous patches V4->V5: 1) rebase to v3.9-rc8-mmotm-2013-04-25-16-24 2) address comments from last round of review We have only tested these patchset on x86 platforms, and have done basic compliation tests using cross-compilers from ftp.kernel.org. That means some code may not pass compilation on some architectures. So any help to test this patchset are welcomed! Patch 1-7: Bugfixes and more work for part1 and part2 Patch 8-9: Fix typo and minor bugs in mm core Patch 10-14: Enhance the way to manage totalram_pages, totalhigh_pages and zone->managed_pages. Patch 15: Report available pages within the node as "MemTotal" for sysfs interface /sys/.../node/nodex/meminfo Jiang Liu (15): mm: fix build warnings caused by free_reserved_area() mm: enhance free_reserved_area() to support poisoning memory with zero mm/ARM64: kill poison_init_mem() mm/x86: use free_reserved_area() to simplify code mm/tile: use common help functions to free reserved pages mm, powertv: use free_reserved_area() to simplify code mm, acornfb: use free_reserved_area() to simplify code mm: fix some trivial typos in comments mm: use managed_pages to calculate default zonelist order mm: accurately calculate zone->managed_pages for highmem zones mm: use a dedicated lock to protect totalram_pages and zone->managed_pages mm: make __free_pages_bootmem() only available at boot time mm: correctly update zone->mamaged_pages mm: concentrate modification of totalram_pages into the mm core mm: report available pages as "MemTotal" for each NUMA node arch/alpha/kernel/sys_nautilus.c | 2 +- arch/alpha/mm/init.c | 6 ++--- arch/alpha/mm/numa.c | 2 +- arch/arc/mm/init.c | 2 +- arch/arm/mm/init.c | 13 ++++----- arch/arm64/mm/init.c | 15 ++--------- arch/avr32/mm/init.c | 6 ++--- arch/blackfin/mm/init.c | 6 ++--- arch/c6x/mm/init.c | 6 ++--- arch/cris/mm/init.c | 4 +-- arch/frv/mm/init.c | 6 ++--- arch/h8300/mm/init.c | 6 ++--- arch/hexagon/mm/init.c | 2 +- arch/ia64/mm/init.c | 4 +-- arch/m32r/mm/init.c | 6 ++--- arch/m68k/mm/init.c | 8 +++--- arch/metag/mm/init.c | 11 +++++--- arch/microblaze/mm/init.c | 6 ++--- arch/mips/mm/init.c | 2 +- arch/mips/powertv/asic/asic_devices.c | 13 ++------- arch/mips/sgi-ip27/ip27-memory.c | 2 +- arch/mn10300/mm/init.c | 2 +- arch/openrisc/mm/init.c | 6 ++--- arch/parisc/mm/init.c | 8 +++--- arch/powerpc/kernel/kvm.c | 2 +- arch/powerpc/mm/mem.c | 7 +++-- arch/s390/mm/init.c | 4 +-- arch/score/mm/init.c | 2 +- arch/sh/mm/init.c | 6 ++--- arch/sparc/mm/init_32.c | 3 +-- arch/sparc/mm/init_64.c | 2 +- arch/tile/mm/init.c | 9 +++---- arch/um/kernel/mem.c | 4 +-- arch/unicore32/mm/init.c | 6 ++--- arch/x86/mm/highmem_32.c | 6 +++++ arch/x86/mm/init.c | 14 +++------- arch/x86/mm/init_32.c | 2 +- arch/x86/mm/init_64.c | 25 ++++------------- arch/xtensa/mm/init.c | 6 ++--- drivers/video/acornfb.c | 28 ++----------------- drivers/virtio/virtio_balloon.c | 8 +++--- drivers/xen/balloon.c | 23 ++++------------ include/linux/bootmem.h | 1 + include/linux/mm.h | 17 ++++++------ include/linux/mmzone.h | 14 +++++++--- mm/bootmem.c | 41 +++++++++++++++++----------- mm/hugetlb.c | 2 +- mm/memory_hotplug.c | 33 +++++------------------ mm/nobootmem.c | 35 ++++++++++++++---------- mm/page_alloc.c | 48 ++++++++++++++++++++------------- 50 files changed, 215 insertions(+), 277 deletions(-) -- 1.7.9.5 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
