I have CONFIG_PM_SLEEP_SMP enabled for imx6q, but still see the imx6q restart hook running on cpu1 than cpu0. It seems that disable_nonboot_cpus is only called in kernel_power_off but never kernel_restart. We should probably patch kernel_restart or machine_restart to have disable_nonboot_cpus called?
