Here is an updated patch, properly split up and with commit messages.
I've tested it on my OMAP3 board an it works. I don't have anything else
to test it with.

Here's a first attempt at allowing IO memory for USERPTR buffers.
It also fixes another issue: it was assumed that
dma->sglen == dma->nr_pages. I'll split that up in a separate patch in the
final version.

Hoi,

I'm implementing zerocopy transfer from a v4l2 camera to the DSP on an
OMAP3 (based on earlier work by Stefan Kost [1][2]). Therefore I'm using
V4L2_MEMORY_USERPTR to pass in the memory area allocated by TI's DMAI
driver. However, this has flags VM
