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 fc374c1f9d7bdcfb851b15b86e58ac5e1f645e32 which is based on mmotm-2013-03-26-15-09. V2->V4: 1) rebase to git://git.cmpxchg.org/linux-mmotm.git 2) fix some build warnings and other minor bugs of previous patches 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
What I interested in is how you test different platform? I don't think you can have all the physical platform.
