Once we have allowed timer interrupts to be enabled during the late phase of suspending devices, we are now able to use the generic pci_set_power_state() to put PCI devices into low power states at that time. We can also use some related platform callbacks, like the ones preparing devices for wake-up, during the late suspend. Doing this will allow us to avoid the race condition where a device using shared interrupts is put into a low power state with interrupts enabled and then an interrupt (for another device) comes in and confuses its driver. At the same time, devices that don't support the native PCI PM or that require some additional, platform-specific operations to be carried out to put them into low power states will be handled as appropriate.
