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!

234 * For now, we'll just check to see if r28 is < (unsigned long)-1024
235 * (to handle addresses > 2 Gb) and if so set r22 to zero. If not,
236 * we'll complement r28 and set r22 to 1. Wrappers will be
237 * needed for syscalls that care about the secondary return value.
238 * The wrapper may also need a way of avoiding the following code,
239 * but we'll deal with that when it becomes necessary.
