There's a bug in the Hitachi SuperH csum_partial_copy_generic()
implementation. If the supplied length is 1 (and several alignment
conditions are met), the function immediately branches to label 4.
However, the assembly at label 4 expects the length to be stored in
register r2. Since this has not occurred, subsequent behavior is
undefined.
This can cause bad payload checksums in TCP connections.
I've fixed the problem by initializing register r2 prior to the branch
instruction.

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!
