Subject: [PATCH v2 0/2] dyndbg: let's use the module notifier callback

Hi,

Jim Cromie hit a BUG() while toggling jump label branches in a module
before they were properly initialized. This isn't currently an issue,
but will be as part of his pending classmap series. Seems like we
should covert to using module callback notifier for dynamic debug
anyways. First patch is just a cleanup.

Thanks,

-Jason
