  • 90f72aa58   mm: add MAP_HUGETLB for mmaping pseudo-anonymous huge page regions ... Browse Code »

    Add a flag for mmap that will be used to request a huge page region that
    will look like anonymous memory to user space. This is accomplished by
    using a file on the internal vfsmount. MAP_HUGETLB is a modifier of
    MAP_ANONYMOUS and so must be specified with it. The region will behave
    the same as a MAP_ANONYMOUS region using small pages.

    The patch also adds the MAP_STACK flag, which was previously defined only
    on some architectures but not on others. Since MAP_STACK is meant to be a
    hint only, architectures can define it without assigning a specific
    meaning to it.

  • 6103ec56c   asm-generic: add generic ABI headers ... Browse Code »

    These header files are typically copied from an existing architecture
    into any new one, slightly modified and then remain untouched until
    the end of time in the name of ABI stability.

    To make it easier for future architectures, provide a sane generic
    version here. In cases where multiple architectures already use
    identical code, I used the most common version. In cases like
    stat.h that are more or less broken everywhere, I provide a
    version that is meant to be ideal for new architectures.

  • 63b852a6b   asm-generic: rename termios.h, signal.h and mman.h ... Browse Code »

    The existing asm-generic versions are incomplete and included
    by some architectures. New architectures should be able
    to use a generic version, so rename the existing files and
    change all users, which lets us add the new files.

  • 5f6164f30   [PATCH] add asm-generic/mman.h ... Browse Code »

    Make new MADV_REMOVE, MADV_DONTFORK, MADV_DOFORK consistent across all
    arches. The idea is to make it possible to use them portably even before
    distros include them in libc headers.

    Move common flags to asm-generic/mman.h
