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: (34 commits) PM: Introduce generic prepare and complete callbacks for subsystems PM: Allow drivers to allocate memory from .prepare() callbacks safely PM: Remove CONFIG_PM_VERBOSE Revert "PM / Hibernate: Reduce autotuned default image size" PM / Hibernate: Add sysfs knob to control size of memory for drivers PM / Wakeup: Remove useless synchronize_rcu() call kmod: always provide usermodehelper_disable() PM / ACPI: Remove acpi_sleep=s4_nonvs PM / Wakeup: Fix build warning related to the "wakeup" sysfs file PM: Print a warning if firmware is requested when tasks are frozen PM / Runtime: Rework runtime PM handling during driver removal Freezer: Use SMP barriers PM / Suspend: Do not ignore error codes returned by suspend_enter() PM: Fix build issue in clock_ops.c for CONFIG_PM_RUNTIME unset PM: Revert "driver core: platform_bus: allow runtime override of dev_pm_ops" OMAP1 / PM: Use generic clock manipulation routines for runtime PM PM: Remove sysdev suspend, resume and shutdown operations PM / PowerPC: Use struct syscore_ops instead of sysdevs for PM PM / UNICORE32: Use struct syscore_ops instead of sysdevs for PM PM / AVR32: Use struct syscore_ops instead of sysdevs for PM ...
