Subject: [PULL] irqdomain/irqchip updates for 4.8

Hi Thomas,

This is a pull request containing the first bunch of updates for
irqdomain and irqchip.

The most important bit is Jon's PM work, which triggered a number of
interesting bug fixes. The ARM GIC is the first driver to make direct
use of this. Also included in this series is Shanker's work
inproducing 2-level translation tables got the GICv3 ITS.

I've given it a good shake, but given that some of the changes are
subtle enough, I'm eager to let it soak in -next for some time.

Thanks,

	M.
