Linux-2.6.12-rc2v2.6.12-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!

+ *
+ * Note that for a big endian machine, this implies that the following
+ * big endian mode connectivity is in place, as described by numerious
+ * ARM documents:
+ *
+ * PCI: D0-D7 D8-D15 D16-D23 D24-D31
+ * ARM: D24-D31 D16-D23 D8-D15 D0-D7
+ *
+ * The machine specific io.h include defines __io to translate an "IO"
+ * address to a memory address.
+ *
+ * Note that we prevent GCC re-ordering or caching values in expressions
+ * by introducing sequence points into the in*() definitions. Note that

+ * deals with the pte side of things.

+ * PGDs:
+ * o The lowest (1) bit of the PGD is to determine if it is present or swap.
+ * o The 2nd bit of the PGD is unused and must be zero.
+ * o The top 6 bits of the PGD must be zero.
+ * PTEs:
+ * o The lower 5 bits of a pte are flags. bit 1 is the 'present' flag. The
+ * others determine the pages attributes.
+ *
+ * the pgd_val, pmd_val, and pte_val macros seem to be private to our code.
+ * They get the RAW value of the PGD/PMD/PTE entry, including our flags
+ * encoded into the pointers.
+ *
+ * The pgd_offset, pmd_offset, and pte_offset macros are used by the kernel,

+/* 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.
