To: linux-arm-kernel
pm_power_off is defined for all architectures. Move it to common code.
Have all architectures call do_kernel_power_off instead of pm_power_off.
Some architectures point pm_power_off to machine_power_off. For those,
call do_kernel_power_off from machine_power_off instead.

v6:
- No change.
v5:
- Rebase to v3.18-rc3
- Update powerpc code to reflect merged power-off handler changes
v4:
- No change
v3:
- Replace poweroff in all newly introduced variables and in text
with power_off or power-off as appropriate
v2:
- do_kernel_poweroff -> do_kernel_power_off
- have_kernel_poweroff -> have_kernel_power_off

To: linux-arm-kernel
Register with kernel power-off handler instead of setting pm_power_off
directly. Register with low priority to reflect that the original code
only sets pm_power_off if it was not already set.
sysctrl_dev is set prior to power-off handler registration, and the
power-off handler is unregistered prior to clearing sysrctrl_dev.
It is therefore not necessary to check if sysctrl_dev is NULL in the
power-off handler, and the check was removed. Setting sysctrl_dev to NULL
in the remove function was also removed as unnecessary. With those changes,
devm_register_power_off_handler can be used to register the poeroff handler.
The now empty remove function was retained since the ab8500_restart function,
which is currently unused, would likely need some cleanup if it was ever used.

v6:
- Moved ab8500_power_off_hb to avoid conflict in -next.
Global: Replaced priority defines with enum.
v5:
- Rebase to v3.18-rc3
v4:
- Do not use notifiers but internal functions and data structures to manage
the list of power-off handlers. Drop unused parameters from callbacks, and
make the power-off function type void
v3:
- Replace poweroff in all newly introduced variables and in text
with power_off or power-off as appropriate
- Replace POWEROFF_PRIORITY_xxx with POWER_OFF_PRIORITY_xxx
v2:
- Use define to specify poweroff handler priority
- Use devm_register_power_off_handler
- Use dev_warn instead of dev_err
- Since we use devm_register_power_off_handler,
we need to check if sysctrl_dev in the poweroff handler to avoid
a race condition on unload, so this check is no longer removed

Register with kernel power-off handler instead of setting pm_power_off
directly. Always use register_power_off_handler_simple as there is no
indication that more than one power-off handler is registered.
If the power-off handler only resets the system or puts the CPU in sleep mode,
select the fallback priority to indicate that the power-off handler is one
of last resort. If the power-off handler powers off the system, select the
default priority.

Register with kernel power-off handler instead of setting pm_power_off
directly.
