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: spi / PM: Support dev_pm_ops PM: Prototype the pm_generic_ operations PM / Runtime: Generic resume shouldn't set RPM_ACTIVE unconditionally PM: Use dev_name() in core device suspend and resume routines PM: Permit registration of parentless devices during system suspend PM: Replace the device power.status field with a bit field PM: Remove redundant checks from core device resume routines PM: Use a different list of devices for each stage of device suspend PM: Avoid compiler warning in pm_noirq_op() PM: Use pm_wakeup_pending() in __device_suspend() PM / Wakeup: Replace pm_check_wakeup_events() with pm_wakeup_pending() PM: Prevent dpm_prepare() from returning errors unnecessarily PM: Fix references to basic-pm-debugging.txt in drivers-testing.txt PM / Runtime: Add synchronous runtime interface for interrupt handlers (v3) PM / Hibernate: When failed, in_suspend should be reset PM / Hibernate: hibernation_ops->leave should be checked too Freezer: Fix a race during freezing of TASK_STOPPED tasks PM: Use proper ccflag flag in kernel/power/Makefile PM / Runtime: Fix comments to match runtime callback code
