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.
