  • 6b3ae58ef   memcg: remove direct page_cgroup-to-page pointer ... Browse Code »

    In struct page_cgroup, we have a full word for flags but only a few are
    reserved. Use the remaining upper bits to encode, depending on
    configuration, the node or the section, to enable page_cgroup-to-page
    lookups without a direct pointer.

    This saves a full word for every page in a system with memory cgroups
    enabled.

  • 37487a565   Add kbuild.h that contains common definitions for kbuild users ... Browse Code »

    The same definitions are used for the bounds logic and the asm-offsets.h
    generation by kbuild. Put them into include/linux/kbuild.h file.

    Also add a new feature

    COMMENT("text")

    which can be used to insert lines of ocmments into asm-offsets.h and
    bounds.h.

  • 97965478a   mm: Get rid of __ZONE_COUNT ... Browse Code »

    It was used to compensate because MAX_NR_ZONES was not available to the
    #ifdefs. Export MAX_NR_ZONES via the new mechanism and get rid of
    __ZONE_COUNT.

  • 9223b4190   pageflags: get rid of FLAGS_RESERVED ... Browse Code »

    NR_PAGEFLAGS specifies the number of page flags we are using. From that we
    can calculate the number of bits leftover that can be used for zone, node (and
    maybe the sections id). There is no need anymore for FLAGS_RESERVED if we use
    NR_PAGEFLAGS.

    Use the new methods to make NR_PAGEFLAGS available via the preprocessor.
    NR_PAGEFLAGS is used to calculate field boundaries in the page flags fields.
    These field widths have to be available to the preprocessor.

  • 1cdf25d70   kbuild: create a way to create preprocessor constants from C expressions ... Browse Code »

    The use of enums create constants that are not available to the preprocessor
    when building the kernel (f.e. MAX_NR_ZONES).

    Arch code already has a way to export constants calculated to the preprocessor
    through the asm-offsets.c file. Generate something similar for the core
    kernel through kbuild.
