unaligned structures coming in off the wire
gcc on arm processors generates very odd code with pragma pack specified -
although it does pack the structures in some sense - it does not allow you
to access unaligned elements in nested structures at the right offset as other
architectures do. Oddly enough though, specifying the structures as packed
the long way - one by one with the packed attribute does work. Rather than
fighting over whether this is a gcc bug or some obscure side effect
of pragma pack, it is easier to do what most (all but 96 other places in
the kernel) do - and replace pragma pack with dozens of attribute(packed)
structure qualifiers. Much more verbose ... but at least it works.

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!
