  Revert "Driver core: let request_module() send a /sys/modules/kmod/-uevent"
  Driver core: fix error by cleanup up symlinks properly
  make kernel/kmod.c:kmod_mk static
  power management: fix struct layout and docs
  power management: no valid states w/o pm_ops
  Driver core: more fallout from class_device changes for pcmcia
  sysfs: move struct sysfs_dirent to private header
  driver core: refcounting fix
  Driver core: remove class_device_rename

* struct pm_ops - Callbacks for managing platform dependent suspend states.
* @valid: Callback to determine whether the given state can be entered.
* If %CONFIG_SOFTWARE_SUSPEND is set then %PM_SUSPEND_DISK is
* always valid and never passed to this call.
* If not assigned, all suspend states are advertised as valid
* in /sys/power/state (but can still be rejected by prepare or enter.)
*
* @prepare: Prepare the platform for the given suspend state. Can return a
* negative error code if necessary.
*
* @enter: Enter the given suspend state, must be assigned. Can return a
* negative error code if necessary.
*
* @finish: Called when the system has left the given state and all devices
* are resumed. The return value is ignored.
*
* @pm_disk_mode: Set to the disk method that the user should be able to
* configure for suspend-to-disk. Since %PM_DISK_SHUTDOWN,
* %PM_DISK_REBOOT, %PM_DISK_TEST and %PM_DISK_TESTPROC
* are always allowed, currently only %PM_DISK_PLATFORM
* makes sense. If the user then choses %PM_DISK_PLATFORM,
* the @prepare call will be called before suspending to disk
* (if present), the @enter call should be present and will
* be called after all state has been saved and the machine
* is ready to be shut down/suspended/..., and the @finish
* callback is called after state has been restored. All
* these calls are called with %PM_SUSPEND_DISK as the state.
