  48 + * Core file format: The core file is written in such a way that gdb
  49 + * can understand it and provide useful information to the user (under
  50 + * linux we use the `trad-core' bfd).  The file contents are as follows:
  51 + *
  52 + *  upage: 1 page consisting of a user struct that tells gdb
  53 + *     what is present in the file.  Directly after this is a
  54 + *     copy of the task_struct, which is currently not used by gdb,
  55 + *     but it may come in handy at some point.  All of the registers
  56 + *     are stored as part of the upage.  The upage should always be
  57 + *     only one page long.
  58 + *  data: The data segment follows next.  We use current->end_text to
  59 + *     current->brk to pick up all of the user variables, plus any memory
  60 + *     that may have been sbrk'ed.  No attempt is made to determine if a
  61 + *     page is demand-zero or if a page is totally unused, we just cover
  62 + *     the entire range.  All of the addresses are rounded in such a way
  63 + *     that an integral number of pages is written.
  64 + *  stack: We need the stack information in order to get a meaningful
  65 + *     backtrace.  We need to write the data from usp to
  66 + *     current->start_stack, so we round each of these in order to be able
  67 + *     to write an integer number of pages.
