[PATCH 03/30] notifier: Add panic notifiers info and purge trailing whitespaces

["Guilherme G. Piccoli" <gpiccoli@xxxxxxxxxx>]

Although many notifiers are mentioned in the comments, the panic
notifiers infrastructure is not. Also, the file contains some
trailing whitespaces. This commit fix both issues.
