Hi,
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.
Greetings,
Rafael
