Merge tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "Only one remaining fix for arm-soc platforms at this time, a small bugfix for cpu hotplug on highbank platforms that has become much easier to hit as of late. Details in the patch description, but it's small and well-contained and definitely impacts users of the platform, so 3.9 seems appropriate." * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: highbank: fix cache flush ordering for cpu hotplug
