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!

PPC can only do rel jumps += 32MB, and often the kernel and other
|
|
modules are furthur away than this. So, we jump to a table of
|
|
trampolines attached to the module (the Procedure Linkage Table)
|
|
whenever that happens.
