I don't understand the math behind this. For any such large number, as
far as I can tell floor(val) == val and hence the end result ought to be
zero. Or doesn't your floor work like that?

[PATCH 00/12] Cherry-pick nv50/nvc0 patches from gallium-nine
I went through the gallium-nine tree and picked out nouveau patches that are
general bug-fixes. The first bunch I'd like to also get into 10.2. I've
reviewed all of them and they make sense to me, but sending them out for
public review as well in case there are any objections.
Unless I hear objections, I'd like to push this by Friday.
