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.
