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!

+ * This is the CPU physical memory map (windows must be at least 64 KB and start
+ * on a boundary that is a multiple of the window size):

+ *    0xf8100000-0xf810ffff      - MV64360 Registers (CONFIG_MV64X60_NEW_BASE)
+ *    0xf8000000-0xf80fffff      - Socketed FLASH
