I didn't give any Reviewed-by tags, much less to revised patches that I've not even looked at yet; please see section 13 of Documentation/SubmittingPatches for what the Reviewed-by tag means.

That said, it would be great if you could review the patches anyway ;)

Also, it looks like this is all based on Laurent's IOMMU probe deferral series which hasn't seen any movement for a while.

Laurent: are you planning to repost that, or is it worth us picking up the original version and bashing it into shape ourselves?

I'd really appreciate if you could take it where I left it and get into shape for upstream. I have no time to work on IOMMU at the moment I'm afraid :-(

No problem at all. It will probably be Robin doing most of the hacking, since he's the platform_device guy and I'm the PCI guy in the office at the moment :)

I think he's also currently got a rebased version of your series with some changes on top, so stay tuned.

I'll try to review patches though.

That would certainly be appreciated, cheers!

Will
