  • 1aadc0560   memblock: s/memblock_analyze()/memblock_allow_resize()/ and update users ... Browse Code »

    The only function of memblock_analyze() is now allowing resize of
    memblock region arrays. Rename it to memblock_allow_resize() and
    update its users.

    * The following users remain the same other than renaming.

    arm/mm/init.c::arm_memblock_init()
    microblaze/kernel/prom.c::early_init_devtree()
    powerpc/kernel/prom.c::early_init_devtree()
    openrisc/kernel/prom.c::early_init_devtree()
    sh/mm/init.c::paging_init()
    sparc/mm/init_64.c::paging_init()
    unicore32/mm/init.c::uc32_memblock_init()

    * In the following users, analyze was used to update total size which
    is no longer necessary.

    powerpc/kernel/machine_kexec.c::reserve_crashkernel()
    powerpc/kernel/prom.c::early_init_devtree()
    powerpc/mm/init_32.c::MMU_init()
    powerpc/mm/tlb_nohash.c::__early_init_mmu()
    powerpc/platforms/ps3/mm.c::ps3_mm_add_memory()
    powerpc/platforms/embedded6xx/wii.c::wii_memory_fixups()
    sh/kernel/machine_kexec.c::reserve_crashkernel()

    * x86/kernel/e820.c::memblock_x86_fill() was directly setting
    memblock_can_resize before populating memblock and calling analyze
    afterwards. Call memblock_allow_resize() before start populating.

    memblock_can_resize is now static inside memblock.c.

  • fe091c208   memblock: Kill memblock_init() ... Browse Code »

    memblock_init() initializes arrays for regions and memblock itself;
    however, all these can be done with struct initializers and
    memblock_init() can be removed. This patch kills memblock_init() and
    initializes memblock with struct initializer.

    The only difference is that the first dummy entries don't have .nid
    set to MAX_NUMNODES initially. This doesn't cause any behavior
    difference.

  • 1c16d242a   memblock: Fix include breakages caused by 24aa07882b ... Browse Code »

    24aa07882b (memblock, x86: Replace memblock_x86_reserve/free_range()
    with generic ones) removed arch/x86/include/asm/memblock.h and dropped
    its inclusion from include/linux/memblock.h which breaks other
    architectures which depended on the generic memblock.h pulling in the
    arch specific one.

    However, the proper fix isn't adding back the asm inclusion. memblock
    doesn't have any arch dependent part and doesn't need arch specific
    header file and asm/memblock.h files are either practically empty or
    contain mostly unrelated arch specific stuff.

    * In microblaze, sh, powerpc, sparc and openrisc, asm/memblock.h is
    either empty or just contains unused MEMBLOCK_DBG() macro. Remove
    them.

    * In arm and unicore32, asm/memblock.h contains arch specific stuff.
    Include it directly from its users. It might be a good idea to
    rename the header file to avoid confusion.

  • 7bf02ea22   arch, mm: filter disallowed nodes from arch specific show_mem functions ... Browse Code »

    Architectures that implement their own show_mem() function did not pass
    the filter argument to show_free_areas() to appropriately avoid emitting
    the state of nodes that are disallowed in the current context. This patch
    now passes the filter argument to show_free_areas() so those nodes are now
    avoided.

    This patch also removes the show_free_areas() wrapper around
    __show_free_areas() and converts existing callers to pass an empty filter.

    ia64 emits additional information for each node, so skip_free_areas_zone()
    must be made global to filter disallowed nodes and it is converted to use
    a nid argument rather than a zone for this use case.

  • b2b755b5f   lib, arch: add filter argument to show_mem and fix private implementations ... Browse Code »

    Commit ddd588b5dd55 ("oom: suppress nodes that are not allowed from
    meminfo on oom kill") moved lib/show_mem.o out of lib/lib.a, which
    resulted in build warnings on all architectures that implement their own
    versions of show_mem():

    lib/lib.a(show_mem.o): In function `show_mem':
    show_mem.c:(.text+0x1f4): multiple definition of `show_mem'
    arch/sparc/mm/built-in.o:(.text+0xd70): first defined here

    The fix is to remove __show_mem() and add its argument to show_mem() in
    all implementations to prevent this breakage.

    Architectures that implement their own show_mem() actually don't do
    anything with the argument yet, but they could be made to filter nodes
    that aren't allowed in the current context in the future just like the
    generic implementation.
