+ * 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).  The 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 handy at some point.  All of the registers
+ *      are stored as part of the upage.  The upage should always be
+ *      only one page long.
+ *  data: The data segment follows next.  We use current->end_text to
+ *      current->brk to pick up all of the user variables, plus any memory
+ *      that may have been sbrk'ed.  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 usp to
+ *      current->start_stack, so we round each of these in order to be able
+ *      to write an integer number of pages.
