How do you want to get these merged? I can take the first 6 patches
through the irqchip tree, and leave the rest to go via the MIPS tree.

Otherwise, if you plan to have the whole thing go via the MIPS tree,
please add my:

Reviewed-by: Marc Zyngier <maz@...nel.org>

to patches 1, 2, 4 and 6.

Please let me know quickly, as I'd like to close the irqchip tree
tomorrow.

Thanks,
