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!

+ * for Atari machines, since the lowest 8 bytes of physical memory are
+ * really ROM (mapped by hardware). For other 680x0 machines: don't
+ * know if it works...
+ *
+ * To get the values at addresses 0 and 4, the MMU better is turned
+ * off first. After that, we have to jump into physical address space
+ * (the PC before the pmove statement points to the virtual address of
+ * the code). Getting that physical address is not hard, but the code
+ * becomes a bit complex since I've tried to ensure that the jump
+ * statement after the pmove is in the cache already (otherwise the
+ * processor can't fetch it!). For that, the code first jumps to the
+ * jump statement with the (virtual) address of the pmove section in
+ * an address register . The jump statement is surely in the cache
+ * now. After that, that physical address of the reset code is loaded
+ * into the same address register, pmove is done and the same jump
+ * statements goes to the reset code. Since there are not many
+ * statements between the two jumps, I hope it stays in the cache.
+ *
+ * The C code makes heavy use of the GCC features that you can get the
+ * address of a C label. No hope to compile this with another compiler
