    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.
