Rich,

why are these changes in linux-next ?

Except I am missing something, I don't see a new version sent for review
on the mailing list. The interrupt controller driver is almost empty as
stated by Marc Zyngier and there is no explanation / discussion about it.

I don't know the goal of adding those patches in linux-next via your
tree, may be you misunderstood how linux-next works and you should
remove them. But if the purpose was to merge the patches, I remind you
that being an arch maintainer does not give you the right to apply any
patches, everywhere, at all cost, without review, because you want them
in, you must follow the process, otherwise you take the risk to upset a
lot of people and to be kicked out.
