Thanks, that is enormously helpful.  Though doing a "diff -Nurp" between 
leb/ti/kernel.git (tag linux-release-2011-11-1) and the tarball that I 
pulled from launchpad 
(https://launchpad.net/~linaro-maintainers/+archive/overlay/+files/linux-linaro-lt-omap_3.1.0-1402.5%7Eoneiric1.tar.gz), 
these two trees aren't exactly the same.  They are *mostly* the same, 
and most of the changes look like they'll be benign to me, but it is a 
bit disconcerting.

In terms of finding things in the future, I have to say that there is a 
bit of a forest of git trees in linaro.  At the very least, I would make 
sure that the .dsc file in the released deb points to the correct 
tree+tag that it was generated from.  Beyond that, I would recommend:

1)  Attempt to reduce the number of trees on git.linaro.org.  I 
understand that there is probably a lot going on, but the sheer number 
of trees makes it confusing.  It might be a good idea to remove some of 
the very stale or no longer active trees.

2)  Document on the wiki where the releases are built from, so there is 
a running record per release

Thanks again,
