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!

+ *
+ * The Tigon uses 64-bit host addresses, regardless of their actual
+ * length, and it expects a big-endian format. For 32 bit systems the
+ * upper 32 bits of the address are simply ignored (zero), however for
+ * little endian 64 bit systems (Alpha) this looks strange with the
+ * two parts of the address word being swapped.
+ *
+ * The addresses are split in two 32 bit words for all architectures
+ * as some of them are in PCI shared memory and it is necessary to use
+ * readl/writel to access them.
+ *
+ * The addressing code is derived from Pete Wyckoff's work, but
+ * modified to deal properly with readl/writel usage.
