    Get UML to use the generic bug support rather than arch specific one.

    If I insert an artificial bug right before loading init, I get this:

    Kernel panic - not syncing: Kernel mode signal 4

    With this patch in place, this is how it looks:

    Kernel panic - not syncing: BUG!

    The BUG changes in -mm3 need some arch support. This patch adds the UML
    support needed. For the most part, it was stolen from the underlying
    architecture. The exception is the kernel eip < PAGE_OFFSET test, which is
    wrong for skas mode UMLs.

    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!
