Mika,

Did you test this patch or just review it?

On my system it doesn't work. I think it has something to do with the
changes to m2m_hw_interrupt but I haven't tracked it down yet.

It looks like what's missing is a:

	edmac->edma->hw_submit(edmac);

But, maybe that's not needed with double buffering?
