    The series,

    Acked-by: Stephen Warren <swarren@nvidia.com>

    (I already saw this a few times before Peter posted it, so any concerns
    I had have been fixed. Still, I'm not very familiar with this part of
    the code, so it'd be awesome if e.g. Colin could review this too)

    Tested-by: Stephen Warren <swarren@nvidia.com>

    (Booted Tegra20 Harmony, validated 2 CPUs found in dmesg during boot,
    validated top showed 2 CPUs being actively used. Booted Tegra30 Cardhu,
    validated 4 CPUs found in dmesg during boot, but didn't validate anything
    from user-space since the SD controller doesn't work yet and I don't have
    an initrd set up to test with).
