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!

Use __KERNEL__ when you're about to use kernel functions,

used by glibc).

Use defined(__KERNEL__) || defined(__elinux__) when doing
|
|
things that only makes sense on an elinux system.
|
|
Use __CRIS__ when you're about to do (really) CRIS-specific code.
