Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

/*
|
|
* 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 actual 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.
|
|
* DATA: The data area is stored. 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 off in order to be
|
|
* able to write an integer number of pages.
