Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/suspend-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/suspend-2.6: PM / Hibernate: Fix preallocating of memory PM / Hibernate: Remove swsusp.c finally PM / Hibernate: Remove trailing space in message PM: Allow SCSI devices to suspend/resume asynchronously PM: Allow USB devices to suspend/resume asynchronously USB: implement non-tree resume ordering constraints for PCI host controllers PM: Allow PCI devices to suspend/resume asynchronously PM / Hibernate: Swap, remove useless check from swsusp_read() PM / Hibernate: Really deprecate deprecated user ioctls PM: Allow device drivers to use dpm_wait() PM: Start asynchronous resume threads upfront PM: Add facility for advanced testing of async suspend/resume PM: Add a switch for disabling/enabling asynchronous suspend/resume PM: Asynchronous suspend and resume of devices PM: Add parent information to timing messages PM: Document device power attributes in sysfs PM / Runtime: Add sysfs switch for disabling device run-time PM
