Merge branch 'syscore' into for-linus
* syscore: 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 PM / Blackfin: Use struct syscore_ops instead of sysdevs for PM ARM / Samsung: Use struct syscore_ops for "core" power management ARM / PXA: Use struct syscore_ops for "core" power management ARM / SA1100: Use struct syscore_ops for "core" power management ARM / Integrator: Use struct syscore_ops for core PM ARM / OMAP: Use struct syscore_ops for "core" power management ARM: Use struct syscore_ops instead of sysdevs for PM in common code
