How to remove origin from git repository

Basic question: How do I disassociate a git repo from the origin from which it was cloned?

git branch -a shows:

* master
  remotes/origin/HEAD -> origin/master

and I want to remove all knowledge of origin, and the associated revisions.

Longer question: I want to take an existing subversion repo and make a number of smaller git repos from it. Each of the new git repos should have the full history of just the relevant branch. I can prune the repo to just the wanted subtree using:

git filter-branch --subdirectory-filter path/to/subtree HEAD

but the resulting repo still contains all the revisions of the now-discarded subtrees under the origin/master branch.

I realise that I could use the -T flag to git-svn to clone the relevant subtree of the subversion repo in the first place. I'm not sure if that would be more efficient than later running multiple instantiations of git filter-branch --subdirectory-filter on copies of the git repo but, in any case, I would still like to break the link with the origin.

Fairly straightforward: 

git remote rm origin

As for the filter-branch question - just add --prune-empty to your filter branch command and it'll remove any revision that doesn't actually contain any changes in your resulting repo:

git filter-branch --prune-empty --subdirectory-filter path/to/subtree HEAD
