I've now applied this to irqchip/unstable with Jonas' Ack to get it some
time in -next.  As the name implies, I can rebase or edit this as
needed.

Since this crosses into arch/openrisc, you may have other changes
depending on it.  If so, just let me know and I'll create a stable topic
branch for you instead of merging it directly into irqchip/core.

thx,

Jason.
