Yes, it is, but I'd rather remove the disable_nonboot_cpus() from power_down() (as Eric suggested) instead of trying to handle the RCU sync problem here. This has been caused by my commit 94985134b7b46848267ed6b734320db01c974e72 (swsusp: disable nonboot CPUs before entering platform suspend) that in such a case should be reverted.
