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!

* There are a number of reasons for patching instructions. Rather than duplicating code
* all over the place, we put the common stuff here. Reasons for patching: in-kernel
* module-loader, virtual-to-physical patch-list, McKinley Errata 9 workaround, and gate
* shared library. Undoubtedly, some of these reasons will disappear and others will
* be added over time.
