The clean-up looks fine as we already have an arm_pm_idle but longer
term I was thinking about having a common declaration similar to
pm_power_off that code under drivers/power/(reset/) can override (and
such driver may be shared by multiple architectures). OTOH, if you get
rid of the generic linux/pm.h declaration architectures can use a common
pm_idle name and type (though I think having it in the common header
would be better). For ARM this would mean s/arm_pm_idle/pm_idle/ on top
if your patch.

Do you have any plans with pm_power_off as well?

Thanks.
