+ * 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, NOT the osf-core). 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.
