Actually, it's a lot simpler than that. We're generating the data for the command, so all we do is send an equivalent command to the array (if any) and then in the irq routine, kmap_atomic the buffer, copy the array data into the buffer in the right order for the command then kunmap the buffer again. This should work fine, I think.
