moving from one SCM that is not syncable with the community to another
is not helping at all. While that clone is great to work *with* git, the
commit ids have nothing to do with the community's one, and we stil have
to convert all the work (to fixup commiter names and so forth too) to be
able to be integrated in the community.

for code archeology, we have many other trees. I'm more interested to be
able to answer things like: 'what commits have never made it to linus ?'
(dmapi, patches that had to be slightly changed) and be able to sort all
our mods in 3 categories: merged-upstream (git-patch-id equality),
partly-merged-upstream (commit title equality), unkonwn-upstream.

I have a tree here, ready to be used to replace the internal ptools
tree, it needs some more work to detect the non-merged part of the
partly-merged-upstream, but well, the diff is mostly whitespaces, and I
guess we can discard them.

Hopefully, this can be widely used RSN.
