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 https://git.kernel.org/pub/scm/linux/kernel/git/mhocko/mm.git since-3.8 Patch 1-6 are minor fixes and furthur work for preview patchset, which uses common helper functions to free reserved pages. Patch 7-11 enhance the way to calculate zone->managed_pages and report available pages as "MemTotal" for each NUMA node Patch 12 concentrates adjusting of totalram_pages, which reduces 37 references to totalram_pages from arch/ subdirectories. 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! There is still another part still under development: Part4: introduce helper functions to simplify mem_init() and remove the global variable num_physpages. Jiang Liu (12): mm: enhance free_reserved_area() to support poisoning memory with zero mm/ARM64: kill poison_init_mem() mm/x86: use common help functions to furthur simplify code mm/tile: use common help functions to free reserved pages mm/powertv: use common help functions to free reserved pages mm/acornfb: use common help functions to free reserved pages mm: accurately calculate zone->managed_pages for highmem zones mm: use a dedicated lock to protect totalram_pages and zone->managed_pages mm: avoid using __free_pages_bootmem() at runtime mm: correctly update zone->mamaged_pages mm: report available pages as "MemTotal" for each NUMA node mm: concentrate adjusting of totalram_pages arch/alpha/kernel/sys_nautilus.c | 2 +- arch/alpha/mm/init.c | 6 ++-- arch/alpha/mm/numa.c | 2 +- arch/arm/mm/init.c | 11 ++++---- 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 | 3 +- arch/ia64/mm/init.c | 4 +-- arch/m32r/mm/init.c | 6 ++-- arch/m68k/mm/init.c | 8 +++--- 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 | 10 +++---- arch/tile/mm/init.c | 9 ++---- arch/um/kernel/mem.c | 4 +-- arch/unicore32/mm/init.c | 6 ++-- arch/x86/mm/highmem_32.c | 5 ++++ arch/x86/mm/init.c | 14 ++-------- arch/x86/mm/init_32.c | 2 +- arch/x86/mm/init_64.c | 24 ++++------------ 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 | 31 ++++----------------- mm/nobootmem.c | 35 +++++++++++++---------- mm/page_alloc.c | 49 ++++++++++++++++++++++----------- 48 files changed, 210 insertions(+), 273 deletions(-) -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
