It's pretty trivial, mostly removing things.  The big problem is Rusty
based his on Linus' tree (and he's offline now), so I need to apply his
patches to that tree and then generate "diff" patches for your tree.

Btw, I'm still having trouble building a "baseline" config using the
cpus4096-v2 branch that actually boots.  (UP boots ok.)  Is this the
correct .git/config:

[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "linus"]
        url = git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
        fetch = +refs/heads/*:refs/remotes/linus/*
[remote "tip"]
        url = git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git
        fetch = +refs/heads/*:refs/remotes/tip/*
[branch "tip-latest"]
        remote = tip
        merge = refs/heads/master
[branch "cpus4096-v2"]
        remote = tip
        merge = refs/heads/cpus4096-v2


It won't let me do a:

mkdir linux-2.6.tip
cd linux-2.6.tip
git-init-db
git-remote add linus git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
git-remote add tip git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git
git-remote update

git-checkout -b cpus4096-v2 tip/cpus4096-v2
git checkout: updating paths is incompatible with switching branches/forcing
Did you intend to checkout 'tip/cpus4906-v2' which can not be resolved as commit?

or:

git-checkout tip/cpus4906-v2
error: pathspec 'tip/cpus4906-v2' did not match any file(s) known to git.
Did you forget to 'git add'?

Thanks,
Mike
