As indicated in a recent thread on Linux-PM, it's necessary to call pm_ops->finish() before devce_resume(), but enable_nonboot_cpus() has to be called before pm_ops->finish() (cf. http://lists.osdl.org/pipermail/linux-pm/2006-November/004164.html). For consistency, it seems reasonable to call disable_nonboot_cpus() after device_suspend(). This way the suspend code will remain symmetrical with respect to the resume code and it may allow us to speed up things in the future by suspending and resuming devices and/or saving the suspend image in many threads. The following series of patches reorders the suspend and resume code so that nonboot CPUs are disabled after devices have been suspended and enabled before the devices are resumed. It also causes pm_ops->finish() to be called after enable_nonboot_cpus() wherever necessary. This patch: Change the ordering of code in kernel/power/main.c so that device_suspend() is called before disable_nonboot_cpus() and pm_ops->finish() is called after enable_nonboot_cpus() and before device_resume(), as indicated by recent discussion on Linux-PM (cf. http://lists.osdl.org/pipermail/linux-pm/2006-November/004164.html).
