Hi Herbert,

I send you this patch alone so that you can verify I'm now properly
manipulating the SG list. Once I have your confirmation I'll send
the whole series again and annoy all the people in Cc one more time
;-).

Thanks.  The only problem that I can see is the fact you're not
checking for req->src == req->dst.  If they're equal then you must
not map it twice.  Instead it should be mapped as DMA_BIDIRECTIONAL.

Cheers,
