Merge branch 'multiplatform/smp_ops' into next/multiplatform
* multiplatform/smp_ops:
ARM: consolidate pen_release instead of having per platform definitions
ARM: smp: Make SMP operations mandatory
ARM: SoC: convert spear13xx to SMP operations
ARM: SoC: convert imx6q to SMP operations
ARM: SoC: convert highbank to SMP operations
ARM: SoC: convert shmobile SMP to SMP operations
ARM: SoC: convert ux500 to SMP operations
ARM: SoC: convert MSM to SMP operations
ARM: SoC: convert Exynos4 to SMP operations
ARM: SoC: convert Tegra to SMP operations
ARM: SoC: convert OMAP4 to SMP operations
ARM: SoC: convert VExpress/RealView to SMP operations
ARM: SoC: add per-platform SMP operations
