I have been waiting for the corresponding mesa patch to get clearance before
pushing this one. Otherwise we risk bringing a regression for an undefined
timespan.
Since I cannot test on PNV, I don't know if it the piglit test still passes
after applying this (and before having the fix in mesa). If you can confirm it
does, then it is no risk to push this already.
