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 Conflicts due to file moves or removals in: arch/arm/mach-msm/board-msm8960.c arch/arm/mach-msm/board-msm8x60.c arch/arm/mach-tegra/board-harmony.c arch/arm/mach-tegra/board-trimslice.c Conflicts due to board file cleanup: arch/arm/mach-tegra/board-paz00.c Conflicts due to cpu hotplug addition: arch/arm/mach-tegra/hotplug.c Signed-off-by: Olof Johansson <olof@lixom.net>
