Ok, pulled this one in, thanks a lot for the patches&review. I think it's
time we start to move on with the next bits, the batch copy stuff seams
like a suitable piece. There's still issues with launching the entire
thing in the end, but we can start with the copy infrastructure.

Open issues I see still:

- The littel issue we're discussing internally. Like I've said that one is
  blocking us and needs to be resolved before we can switch to enforcing

- Secure batch dispatch is still fubar.

- CodingStyle says: Functions should be a) at most 3 indent levels b) at
  most 3 ansi screens long (i.e. 75 lines). i915_parse_cmds violates both
  metrics pretty deftly. I think a few refactoring patches to extract
  helper functions and structure the flow a bit would be good.

Cheers, Daniel
