Too many parameters for drupal_alter

I wanted to alter the list of administrative links presented on the overview page for a particular entity [bundle], so I was happy to see it was alterable via hook_panelizer_overview_links_alter(). However, it looks as though the drupal_alter invocation is using an old syntax, so that only the first three of the seven parameters are passed through to alter hook implementations. I changed it as captured in the attached patch (passing the extra vars in an array), and it is working perfectly for me now. This looks like the right approach if I understand the drupal_alter documentation correctly (but feel free to correct me if I don't!).
