Merge tag 'cleanup-initcall' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull sweeping late_initcall cleanup for arm-soc from Olof Johansson: "This is a patch series from Shawn Guo that moves from individual late_initcalls() to using a member in the machine structure to invoke a platform's late initcalls. This cleanup is a step in the move towards multiplatform kernels since it would reduce the need to check for compatible platforms in each and every initcall." Fix up trivial conflicts in arch/arm/mach-{exynos/mach-universal_c210.c, imx/mach-cpuimx51.c, omap2/board-generic.c} due to changes nearby (and, in the case of cpuimx51.c the board support being deleted) * tag 'cleanup-initcall' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: ux500: use machine specific hook for late init ARM: tegra: use machine specific hook for late init ARM: shmobile: use machine specific hook for late init ARM: sa1100: use machine specific hook for late init ARM: s3c64xx: use machine specific hook for late init ARM: prima2: use machine specific hook for late init ARM: pnx4008: use machine specific hook for late init ARM: omap2: use machine specific hook for late init ARM: omap1: use machine specific hook for late init ARM: msm: use machine specific hook for late init ARM: imx: use machine specific hook for late init ARM: exynos: use machine specific hook for late init ARM: ep93xx: use machine specific hook for late init ARM: davinci: use machine specific hook for late init ARM: provide a late_initcall hook for platform initialization
