That's what you deserve, for using svn at your side ;-)

But if you want to transfer revisions from LLVM's svn to your svn repo,
maybe you can do that:

(Upstream) svn <--> git-svn <--> svn (Downstream)

You would use two git-svn branches on the git repo, one for each svn
repo, and merge revisions among the two. I'm not user if that's
possible, though. Another option is to use two git-svn repos:

(Upstream) svn <--> git-svn <--> git-svn <--> svn (Downstream)

The difficult part is not on LLVM's using svn, the problem is on you
using svn.

And for a git mirror that pushes changes to the LLVM svn repo, that's
*way* more tricky than it seems.
