* 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.
