Merge tag 'fixes-nc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC non-critical fixes from Olof Johansson: "Here is a collection of fixes (and some intermixed cleanups) that were considered less important and thus not included in the later parts of the 3.9-rc cycle. It's a bit all over the map, contents wise. A series of ux500 fixes and cleanups, a bunch of various fixes for OMAP and tegra, and some for Freescale i.MX and even Qualcomm MSM. Note that there's also a patch on this branch to globally turn off -Wmaybe-uninitialized when building with -Os. It's been posted several times by Arnd and no dissent was raised, but nobody seemed interested to pick it up. So here it is, as the topmost patch." * tag 'fixes-nc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (70 commits) Turn off -Wmaybe-uninitialized when building with -Os ARM: orion5x: include linux/cpu.h ARM: tegra: call cpu_do_idle from C code ARM: u300: fix ages old copy/paste bug ARM: OMAP2+: add dependencies on ARCH_MULTI_V6/V7 ARM: tegra: solve adr range issue with THUMB2_KERNEL enabled ARM: tegra: fix relocation truncated error when THUMB2_KERNEL enabled ARM: tegra: fix build error when THUMB2_KERNEL enabled ARM: msm: Fix uncompess.h tx underrun check ARM: vexpress: Remove A9 PMU compatible values for non-A9 platforms ARM: cpuimx27 and mbimx27: prepend CONFIG_ to Kconfig macro ARM: OMAP2+: fix typo "CONFIG_BRIDGE_DVFS" ARM: OMAP1: remove "config MACH_OMAP_HTCWIZARD" ARM: mach-imx: mach-imx6q: Fix sparse warnings ARM: mach-imx: src: Include "common.h ARM: mach-imx: gpc: Include "common.h" ARM: mach-imx: avic: Staticize *avic_base ARM: mach-imx: tzic: Staticize *tzic_base ARM: mach-imx: clk: Include "clk.h" ARM: mach-imx: clk-busy: Staticize clk_busy_mux_ops ...
