ARM64 will be the > only arch setting it at least for the time being, is that correct? HW reduced only platforms are still required to support sleep states that on arm64 are totally meaningless at present, so I do not think ACPI_REDUCED_HARDWARE_ONLY will cut it. Factoring out power_off methods from sleep.c ? I know, it is not nicer since you split the S-states management in multiple files. Side note: is the acpi_suspend() function in sleep.c used in the kernel ?
