    Whole series applied to mvebu-next/irqchip-fixes (v2 for 3/3). Once I
    see that the outstanding pull requests for mvebu/irqchip have been
    merged into mainline, I'll be changing the name of this branch to
    mvebu/irqchip-fixes. I just don't want to upset the applecart atm.

    Oh yeah, Cc'd for stable back to v3.10.

    thx,

    Jason.
