Patch 1 of this series implements the restart handler function. Patches 2 and 3
implement calling the restart handler chain from arm and arm64 restart code.
Patch 4 modifies the restart-poweroff driver to no longer call arm_pm_restart
directly but machine_restart. This is done to avoid calling arm_pm_restart
from more than one place. The change makes the driver architecture independent,
so it would be possible to drop the arm dependency from its Kconfig entry.
Patch 5 and 6 convert existing restart handlers in the watchdog subsystem
to use the restart handler. Patch 7 unexports arm_pm_restart to ensure
that no one gets the idea to implement a restart handler as module.
For the current patches:

Do you plan to convert more of the power/drivers/reset/ code?
Once this series has been accepted, I at least wanted to give it a try.
BTW, is it worth doing something similar for pm_power_off (there is
generic code calling it directly, so slightly more complicated than
pm_restart)?
I have not thought about it yet.
A quick glance suggests it is much more widely used than the reset handler.
It looks like the original idea, like with machine_restart, was to have
one function per architecture, but it seems that is widely abused.
Looks pretty messy to me. Maybe after this one is done, if there is interest
and, more importantly, the need to do something about it.
Thanks,
Guenter
