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!

+ *
+ * If the address does not span a 4GB page boundary, the contents of @ne_addr
+ * and @ne_len are undefined.  @e_len is updated to reflect a normalization.
+ *
+ * Example:
+ *
+ * 	ffffabc0ffffeeee	(e_addr) start of DMA address
+ * 	0000000020000000	(e_len)  length of DMA transfer
+ *	ffffabc11fffeeed	end of DMA transfer
+ *
+ * Is the 4GB boundary crossed?
+ *
+ * 	ffffabc0ffffeeee	(e_addr)

+ *	00000001e0000003	((e_addr ^ (e_addr + e_len - 1))
+ *	0000000100000000	((e_addr ^ (e_addr + e_len - 1)) & ~(0xffffffff)

+ * Compute start of second DMA segment:
+ *
+ * 	ffffabc0ffffeeee	(e_addr)
+ *	ffffabc1ffffeeee	(0x100000000 + e_addr)
+ *	ffffabc100000000	(0x100000000 + e_addr) & ~(0xffffffff)
+ *	ffffabc100000000	(ne_addr)
+ *	
+ * Compute length of second DMA segment:
+ *
+ *	00000000ffffeeee	(e_addr & 0xffffffff)
+ *	0000000000001112	(0x100000000 - (e_addr & 0xffffffff))
+ *	000000001fffeeee	(e_len - (0x100000000 - (e_addr & 0xffffffff))
+ *	000000001fffeeee	(ne_len)
+ *
+ * Adjust length of first DMA segment
+ *
+ * 	0000000020000000	(e_len)
+ *	0000000000001112	(e_len - ne_len)
