Re-spun as suggested. I think this should be i-series friendly.

During power outages, the ups notifies the system for a shutdown. In the
current setup, it isn't possible to poweron when power is restored. This
patch fixes the issue by calling the right ibm,power-off-ups token
during such events. It also adds a sysfs interface so that rc.powerfail
can parse the epow events and modify the power-off behavior accordingly
to enable the right token to be called.
