Nick, I'm not going to apply this patch, simply because the effort of
verifying that you haven't made a mistake is greater than the gain we
might get from applying it.  Your earlier patch shows that you haven't
actually learned anything since I first heard about your patches.
Please, continue learning before submitting more patches.

The driver does use functions defined in linux/mm.h: get_user_pages_fast
is one of them. It compiles without including the header because another
we include includes mm.h, but we don't want to depend on that!

Don't worry, I didn't waste time checking; I just happened to know that
one off the top.
