    +/* Core file format: The core file is written in such a way that gdb
    + * can understand it and provide useful information to the user (under
    + * linux we use the 'trad-core' bfd). There are quite a number of
    + * obstacles to being able to view the contents of the floating point

    + * the contents of them. Actually, you can read in the core file and
    + * look at the contents of the user struct to find out what the
    + * floating point registers contain.
    + *
    + * The actual file contents are as follows:
    + * UPAGE:
    + * 1 page consisting of a user struct that tells gdb what is present
    + * in the file. Directly after this is a copy of the task_struct,
    + * which is currently not used by gdb, but it may come in useful at
    + * some point. All of the registers are stored as part of the
    + * upage. The upage should always be only one page.
    + *
    + * DATA:
    + * The data area is stored. We use current->end_text to
    + * current->brk to pick up all of the user variables, plus any
    + * memory that may have been malloced. No attempt is made to
    + * determine if a page is demand-zero or if a page is totally
    + * unused, we just cover the entire range. All of the addresses are
    + * rounded in such a way that an integral number of pages is
    + * written.
    + *
    + * STACK:
    + * We need the stack information in order to get a meaningful
    + * backtrace. We need to write the data from (esp) to
    + * current->start_stack, so we round each of these off in order to
    + * be able to write an integer number of pages. The minimum core
