Subject: [Resend][PATCH 0/9] PM: Update global suspend and hibernation operations framework

Hi,

This series of patches implements changes that are possible/necessary/desirable
(IMO) after the introduction of the .set_target() method in 'struct pm_ops' (commit
2391dae3e36c19fe668c71eac2eb8344dbaaf46d).

The patches in the series make the following changes:
* make ACPI use the new .set_target() method in 'struct pm_ops'
* add an ACPI helper function for the devices to determine the power state
  to put the device into
* move the definition of 'struct pm_ops' to <include/suspend.h>
* change the name of 'struct pm_ops' to 'struct platform_suspend_ops' and
  modify the names of some related functions and global variables accordingly
* modify 'struct platform_suspend_ops' so that .prepare() and .finish() don't
  take arguments (.enter() still takes the state argument, because some
  platforms don't need to implement the other callbacks)
* make some functions normally defined in kernel/power/main.c be also defined
  when CONFIG_PM is unset
* make suspend_ops be a static variable
* rework 'struct hibernation_ops' to add the new method analogous to
  .set_target()
* rename 'struct hibernation_ops' to 'struct platform_hibernation_ops' (in
  analogy with 'struct platform_suspend_ops')

The series in on top of the current -git with the following patches, currently
in -mm or in the ACPI tree, applied:

swsusp-remove-incorrect-code-from-userc.patch
swsusp-remove-code-duplication-between-diskc-and-userc.patch
swsusp-introduce-restore-platform-operations.patch
swsusp-fix-hibernation-code-ordering.patch
hibernation-prepare-to-enter-the-low-power-state.patch
pm-introduce-hibernation-and-suspend-notifiers.patch
acpi-do-not-attempt-to-run-s1-standby-workarounds-while-hibernating.patch
pm-reduce-code-duplication-between-mainc-and-userc-updated.patch

Greetings,
Rafael
