Testing this series on top of v3.13-rc3, plus a couple of other
necessary changes (which should've probably been noted in the changelog):

1) change CONFIG_NR_CPUS=8 in .config
2) add the exynos combiner patch from Chander:
   [PATCH v2] irqchip: exynos-combiner: remove hard-coded irq_base value

I'm still only seeing 2 out of 4 cores come up on my odroid-xu:

[    0.045000] CPU: Testing write buffer coherency: ok
[    0.045000] CPU0: update cpu_power 1024
