I have collected Tony's and Laurent's Acked-by's and amended them to
the commit logs.

I have also made sure it applies cleanly to a recent 3.2, and tested
it with OMAP4/remoteproc. I couldn't test it with omap3isp though,
because I'm gated by (what looks like a) 3.2 omap3isp regression (see
http://www.spinics.net/lists/linux-omap/msg60510.html). I did test it
of course with omap3isp and 3.1, so I don't expect any omap3isp/iommu
issues with these patches. Anyway, when the omap3isp issue will be
resolved I'll make sure there isn't any iommu regression.

Please pull, thanks a lot!
