    increase AT_VECTOR_SIZE to terminate saved_auxv properly · 4f9a58d7

    include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO.  fs/binfmt_elf.c
    has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT
    entries.  So in the worst case, saved_auxv does not get an AT_NULL entry at
    the end.
    
    The saved_auxv array must be terminated with an AT_NULL entry.  Make the
    size of mm_struct->saved_auxv arch dependend, based on the number of
    ARCH_DLINFO entries.
