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!

+The SGI Visual Workstations (models 320 and 540) are based around
+the Cobalt, Lithium, and Arsenic ASICs.  The Cobalt ASIC is the
+main system ASIC which interfaces the 1-4 IA32 cpus, the memory
+system, and the I/O system in the Lithium ASIC.  The Cobalt ASIC
+also contains the 3D gfx rendering engine which renders to main
+system memory -- part of which is used as the frame buffer which
+is DMA'ed to a video connector using the Arsenic ASIC.  A PIIX4
+chip and NS87307 are used to provide legacy device support (IDE,
+serial, floppy, and parallel).
+
+The Visual Workstation chipset largely conforms to the PC architecture
+with some notable exceptions such as interrupt handling.
