Merge branches 'pm-cpuidle' and 'pm-tools'
* pm-cpuidle:
cpuidle: poll_state: Avoid invoking local_clock() too often
PM: cpuidle/suspend: Add s2idle usage and time state attributes
cpuidle: Enable coupled cpuidle support on Exynos3250 platform
cpuidle: poll_state: Add time limit to poll_idle()
ARM: cpuidle: Drop memory allocation error message from arm_idle_init_cpu()
* pm-tools:
pm-graph: AnalyzeSuspend v5.0
pm-graph: AnalyzeBoot v2.2
pm-graph: config files and installer
