  • 1fcccbac8   elf coredump: replace ELF_CORE_EXTRA_* macros by functions ... Browse Code »

    elf_core_dump() and elf_fdpic_core_dump() use #ifdef and the corresponding
    macro for hiding _multiline_ logics in functions. This patch removes
    #ifdef and replaces ELF_CORE_EXTRA_* by corresponding functions. For
    architectures not implemeonting ELF_CORE_EXTRA_*, we use weak functions in
    order to reduce a range of modification.

    This cleanup is for my next patches, but I think this cleanup itself is
    worth doing regardless of my firnal purpose.

  • 2f79e48ae   x86: compat_binfmt_elf ... Browse Code »

    This adds fs/compat_binfmt_elf.c, a wrapper around fs/binfmt_elf.c for
    32-bit ELF support on 64-bit kernels. It can replace all the hand-rolled
    versions of this that each 32/64 arch has, which are all about the same.

    To use this, an arch's asm/elf.h has to define at least a few compat_*
    macros that parallel the various macros that fs/binfmt_elf.c uses for
    native support.

    There is no attempt to deal with compat macros for the core dump format
    support. To use this file, the arch has to define compat_gregset_t for
    linux/elfcore-compat.h and #define CORE_DUMP_USE_REGSET. The 32-bit
    compatible formats should come automatically from task_user_regset_view
    called on a 32-bit task.
