Linux-2.6.12-rc2
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). There are quite a number of
+ * obstacles to being able to view the contents of the floating point
+ * registers, and until these are solved you will not be able to view
+ * the contents of them. Actually, you can read in the core file and
+ * look at the contents of the user struct to find out what the
+ * floating point registers contain.
+ *
+ * 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 useful 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 malloced. 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 (esp) to
+ * current->start_stack, so we round each of these off in order to
+ * be able to write an integer number of pages. The minimum core
+ * file size is 3 pages, or 12288 bytes.
