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."
