<pre>I'm pretty sure this happens because we wind up re-computing the same watermark
values for each CRTC multiple times in a single atomic transaction (once per
CRTC involved in the transaction). I'm putting together some patches that make
SKL watermarks play more nicely with atomic (and eliminate this unnecessary
looping); I should have those ready to post next week sometime.</pre>
