Merge tag 'pm-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management updates for 3.4 from Rafael Wysocki: "Assorted extensions and fixes including: * Introduction of early/late suspend/hibernation device callbacks. * Generic PM domains extensions and fixes. * devfreq updates from Axel Lin and MyungJoo Ham. * Device PM QoS updates. * Fixes of concurrency problems with wakeup sources. * System suspend and hibernation fixes." * tag 'pm-for-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (43 commits) PM / Domains: Check domain status during hibernation restore of devices PM / devfreq: add relation of recommended frequency. PM / shmobile: Make MTU2 driver use pm_genpd_dev_always_on() PM / shmobile: Make CMT driver use pm_genpd_dev_always_on() PM / shmobile: Make TMU driver use pm_genpd_dev_always_on() PM / Domains: Introduce "always on" device flag PM / Domains: Fix hibernation restore of devices, v2 PM / Domains: Fix handling of wakeup devices during system resume sh_mmcif / PM: Use PM QoS latency constraint tmio_mmc / PM: Use PM QoS latency constraint PM / QoS: Make it possible to expose PM QoS latency constraints PM / Sleep: JBD and JBD2 missing set_freezable() PM / Domains: Fix include for PM_GENERIC_DOMAINS=n case PM / Freezer: Remove references to TIF_FREEZE in comments PM / Sleep: Add more wakeup source initialization routines PM / Hibernate: Enable usermodehelpers in hibernate() error path PM / Sleep: Make __pm_stay_awake() delete wakeup source timers PM / Sleep: Fix race conditions related to wakeup source timer function PM / Sleep: Fix possible infinite loop during wakeup source destruction PM / Hibernate: print physical addresses consistently with other parts of kernel ...
