Pulled into next/dt, thanks a lot!
Unfortunately, this got two conflicts against "ARM: exynos4: convert to
CONFIG_MULTI_IRQ_HANDLER" from Marc Zyngier, and I suspect my temporary
resolution is incorrect:

The other conflict was a one-line change from 1fb3726cf3 "ARM: SAMSUNG: Move timer irq
numbers to end of linux irq space" (from Thomas Abraham) in code that was removed
by Marc's patch, so I kept removing that.
Maybe you can do a merge of your branch with Russell's devel-stable branch and tell me
which conflict resolution you would like.
