Hi,

How can I get the _real_ address of a pci_map_single area, if needed? The 
thing bus_to_virt() did, basically. My problem is that I have code which 
changed the first byte of a buffer of stuff read via DMA, and I can't 
because the previous user did bus_to_virt() to get a pointer into that. I 
don't know how to get another pointer.

After all the confusion, is the question clear?

							Regards,
							Thunder
