2006-11-23  Soren Sandmann <sandmann@daimi.au.dk>

        * process.c (read_maps): Set inode for vdso to 0.

        * binfile.c (read_inode): Return -1 on error, 0 on vdso
        (bin_file_new): Only read the inode if the file actually exists
        and is an elf file.
        (bin_file_check_inode): Return FALSE if there is no file.
