Theoretically, that surely is correct, and which is what the patch actually does. :-) Still, we have users for whom hibernation was broken by moving the execution of acpi_leave_sleep_state() before enable_nonboot_cpus(). At least on one of these systems the hibernation can be fixed by removing the execution of acpi_leave_sleep_state() from before enable_nonboot_cpus() and adding a simplified version of it that only executes _WAK and enables the GPEs *after* device_resume(). Unfortunately, I was unable to check if _WAK was necessary for this (I hope it wasn't).
